Anglerfish flat prey crossword clue 7 letters. Monkfish: description, habitat and interesting facts. Description of monkfish

Monkfish, or anglerfish, is a predatory sea bottom fish that belongs to the class ray-finned fish, subclass new-finned fish, infraclass bony fish, order anglerfish, suborder anglerfish, family anglerfish, genus anglerfish (large anglerfish), or sea devils (lat. Lophius).

Etymology Latin name monkfish not fully understood. Some scientists are of the opinion that it came from a modified Greek word"λοφίο", denoting a ridge that resembles the jaws of this fish. Other researchers associate it with a kind of ridge running along the entire back. The popular name “anglerfish” appeared due to the long and modified first ray of the dorsal fin, equipped with a bait (eska) and resembling a fisherman’s fishing rod. And thanks to the unusual and unattractive appearance of the predator’s head, it was nicknamed “monkfish”. Due to the fact that angler fish can move along the seabed, pushing off from it with slightly modified fins, in some countries fishermen call them frogs.

Monkfish (fish) – description, structure, photo. What does monkfish look like?

Sea devils are fairly large predatory fish that live on the bottom and reach a length of 1.5-2 meters. The weight of monkfish is 20 kilograms or more. The body and huge head with small gill slits are quite strongly flattened in the horizontal direction. In almost all species of anglerfish, the mouth is very wide and opens almost over the entire circumference of the head. The lower jaw is less mobile than the upper jaw and is slightly pushed forward. Predators are armed with rather large sharp teeth that are curved inward. Thin and flexible jaw bones enable fish to swallow prey that is almost twice their size.

The monkfish's eyes are small, set close together, and located on the top of the head. The dorsal fin consists of two parts separated from each other, one of which is soft and shifted towards the tail, and the second is folded into six rays, three of which are located on the head itself, and three immediately behind it.

The anterior spiny ray of the dorsal fin is strongly shifted towards the upper jaw and represents a kind of “rod”; on its top there is a leathery formation (esca), in which luminous bacteria live, which are bait for potential prey.

Due to the fact that the pectoral fins of the monkfish are reinforced by several skeletal bones, they are quite powerful and allow the fish not only to burrow into the bottom soil, but also to move along it by crawling or using peculiar jumps. The pelvic fins are less in demand during the movement of the angler fish and are located on the throat.

It is noteworthy that the body of the anglerfish, painted in dark gray or dark brown colors (often with chaotically located light spots), is covered not with scales, but with various spine-like projections, tubercles, and long or curly leathery fringe, similar to algae. This camouflage allows the predator to easily set up an ambush in thickets of algae or on a sandy bottom.

Where does the anglerfish (monkfish) live?

The distribution area of ​​the genus of anglerfish is quite extensive. It includes the western waters of the Atlantic Ocean, which washes the shores of Canada and the United States of America, the eastern Atlantic, whose waves crash against the shores of Iceland and the British Isles, and the cooler depths of the North, Barents and Baltic seas. Certain species of monkfish are found near the coasts of Japan and Korea, in the waters of the Okhotsk and Yellow Seas, in the Eastern part Pacific Ocean and in the Black Sea. Anglerfish also live in the depths Indian Ocean, covering the southern tip African continent. Depending on the species, sea devils live at depths from 18 meters to 2 kilometers or more.

What does monkfish (anglerfish) eat?

In terms of feeding, sea devils are predators. The basis of their diet consists of fish that live in the bottom layer of water. The stomachs of anglerfish include gerbils and cod, small stingrays and small sharks, eels, flounders, cephalopods(squid, cuttlefish) and various crustaceans. Sometimes these predators rise closer to the surface of the water, where they hunt for herring or mackerel. Including cases where anglerfish even attacked birds peacefully rocking on the sea waves.

All sea devils hunt from ambush. Thanks to their natural camouflage, it is impossible to notice them when they lie motionless on the bottom, buried in the ground or hidden in thickets of algae. Potential prey is attracted by a luminous bait, which is located at the end of a kind of fishing rod - an elongated ray of the anterior dorsal fin. The moment a passing crustacean, invertebrate or fish touches the esky, angler sharply opens its mouth. As a result of this, a vacuum is formed, and a stream of water, along with the victim, who does not have time to do anything, rushes into the mouth of the predator, because the time it takes does not exceed 6 milliseconds.

While waiting for prey, the monkfish fish is able to remain absolutely motionless for a long time and hold its breath. The pause between breaths can last from one to two minutes.

Previously, it was believed that the monkfish “fishing rod” with bait, movable in all directions, serves to attract prey, and anglerfish open their large mouths only when they touch the fishing rod of curious fish. However, scientists were able to establish that the mouth of predators automatically opens, even if any object passing by touches the bait.

Angler fish are quite greedy and gluttonous. This often leads to their death. Having a mouth and a stomach large sizes, monkfish is capable of capturing enough big catch. Because of the sharp and long teeth, the hunter cannot let go of his prey, which does not fit in his stomach, and chokes on it. There are known cases when fishermen found prey in the belly of a caught predator that was only 7-10 cm smaller than the monkfish itself.

Types of monkfish (anglerfish), names and photos

The genus of anglerfish (lat. Lophius) currently includes 7 species:

1. Lophius americanus (Valenciennes, 1837) – American anglerfish (American monkfish)
2. Lophius budegassa (Spinola, 1807) – black-bellied anglerfish, or southern European anglerfish, or budegassa anglerfish
3. Lophius gastrophysus (Miranda Ribeiro, 1915) – Western Atlantic anglerfish
4. Lophius litulon (Jordan, 1902) – Far Eastern monkfish, yellow anglerfish, Japanese anglerfish
5. Lophius piscatorius (Linnaeus, 1758) – European monkfish
6. Lophius vaillanti (Regan, 1903) – South African anglerfish
7. Lophius vomerinus (Valenciennes, 1837) – Cape (Burmese) monkfish

Below is a description of several types of anglerfish.

• American monkfish (American anglerfish) ( Lophius americanus)

This is a dimersal (bottom-dwelling) predatory fish, having a length from 0.9 m to 1.2 m with a body weight of up to 22.6 kg. Thanks to its huge rounded head and body tapering towards the tail, the American anglerfish resembles a tadpole. The lower jaw of the large wide mouth is strongly pushed forward. It is noteworthy that even with its mouth closed, this predator’s lower teeth are visible. Both the upper and lower jaws are literally studded with sharp thin teeth, inclined deep into the mouth and reaching a length of 2.5 cm. Interestingly, in the lower jaw, almost all monkfish teeth big size and are arranged in three rows. On the upper jaw, large teeth grow only in the center, and in the lateral areas they are smaller, and there are also small teeth at the top of the oral cavity. The gills, lacking covers, are located immediately behind the pectoral fins. Monkfish eyes small size directed upwards. Like all anglerfish, the first ray is elongated and has a leathery growth that glows due to the bacteria that have settled there. The leathery coverings of the back and sides are colored chocolate brown in various shades and covered with small light or dark spots, while the belly is dirty white. The lifespan of this species of monkfish can reach 30 years. The distribution area of ​​the American anglerfish includes the northwestern part of the Atlantic Ocean with depths of up to 670 m, stretching from the Canadian provinces of Newfoundland and Quebec to the northeastern coast of the North American state of Florida. This predator thrives in waters with temperatures from 0°C to +21°C on sandy, gravel, clay or silty bottom sediments, including those covered with destroyed shells of dead mollusks.

• European anglerfish(European monkfish) ( Lophius piscatorius)

It reaches a length of 2 meters, and the weight of individual individuals exceeds 20 kg. The entire body of these predators is flattened from the back to the belly. The size of the wide head can be 75% of the length of the entire fish. The European monkfish has a huge crescent-shaped mouth with a large number of thin, pointed, slightly hooked teeth, and a lower jaw that is significantly pushed forward. Slit-like gill openings are located behind the wide, skeletal-reinforced pectoral fins that allow European anglerfish to move along or burrow along the bottom. The soft, scaleless body of these bottom-dwelling fish is covered with a variety of bony spines or leathery growths of various lengths and shapes. The same “decorations” in the form of a beard border the jaws and lips, as well as lateral surface European monkfish heads. The posterior dorsal fin is located opposite the anal fin. The anterior dorsal fin consists of 6 rays, the first of which is located on the anglerfish’s head and can reach a length of 40-50 cm. At its top there is a leather “bag” that glows in the dark layers of bottom water. The coloring of individuals varies somewhat depending on the habitat of these fish. The back and sides, covered with dark spots, can be colored brown, reddish or greenish-brown, in contrast to the belly, which is white. The European monkfish lives in the Atlantic Ocean, which washes the shores of Europe, from the coast of Iceland to the Gulf of Guinea. These “cute creatures” can be found not only in the cold waters of the North, Baltic and Barents Seas or in the English Channel, but also in the warmer Black Sea. European anglerfish live at depths from 18 to 550 m.

• Black-bellied anglerfish (South European anglerfish, Budegassa anglerfish) ( Lophius budegassa)

In structure and shape, this species of marine fish is very close to its European relative, but unlike it, it has a more modest size and a head that is not so wide relative to the body. The length of the monkfish ranges from 0.5 to 1 meter. The structure of the jaw apparatus is no different from individuals of other species. This species of monkfish gets its name from its characteristic black abdomen, while its back and sides are colored various shades reddish-brown or pinkish-gray in color. Depending on their habitat, the body of some individuals may be covered with dark or light spots. The leathery outgrowths of a yellowish or light sandy color that border the jaws and head of the black-bellied anglerfish are short in length and located quite sparsely. The lifespan of the black-bellied monkfish does not exceed 21 years. This species is widespread in the waters of the eastern part of the Atlantic Ocean throughout the entire space - from Great Britain and Ireland to the coast of Senegal, where the monkfish lives at depths from 300 to 650 m. The black-bellied anglerfish can also be found in the waters of the Mediterranean and Black Seas at depths of up to 1 kilometer

• Far Eastern monkfish (yellow anglerfish, Japanese anglerfish) ( Lophius litulon)

It is a typical inhabitant of the waters of the Sea of ​​Japan, Okhotsk, Yellow and East China Seas, as well as a small part of the Pacific Ocean off the coast of Japan, where it is found at depths ranging from 50 m to 2 km. Individuals of this species grow up to 1.5 meters in length. Like all representatives of the genus Lophius, the Japanese monkfish has a horizontally flattened body, but unlike its relatives it has more a long tail. Sharp teeth curved towards the throat in the lower, forward jaw are arranged in two rows. The leathery body of the yellow anglerfish, covered with numerous outgrowths and bony tubercles, is colored in a single color. Brown color, over which light spots with darker outlines are randomly scattered. Unlike the back and sides, the belly of Far Eastern monkfish is light. The dorsal, anal and pelvic fins are dark in color, but have light tips.

• Cape Anglerfish, or Burmese monkfish, ( Lophius vomerinus)

It is distinguished by a huge flattened head and a rather short tail, occupying less than one third of the length of the entire body. The size of adult individuals does not exceed 1 meter. Their life expectancy is no more than 11 years. The Cape anglerfish lives at depths of 150 to 400 m in the southeastern Atlantic and western Indian Ocean, along the coasts of Namibia, Mozambique and the Republic of South Africa. The light brown body of the Burmese monkfish is strongly flattened from the back towards the abdomen and covered with a fringe of numerous leathery growths. The esca, located at the top of the long first ray of the dorsal fin, resembles a flap. The gill slits are located behind the pectoral fins and just below their level. The lower part of the body (abdomen) is lighter, almost white.

Reproduction of anglerfish (monkfish)

To spawn, females and males of monkfish descend to depths from 0.4 km to 2 km. In southern latitudes, the mating season of fish occurs at the end of winter or beginning of spring. In the northern regions, this time shifts to mid-spring - early summer, and for Japanese monkfish, spawning begins at the end of summer. Having descended into deep water, female anglerfish begin to spawn, and males cover them with milk. After the mating season, hungry adult females and males swim to shallow water, where they feed intensively until the fall, preparing for wintering at great depths.

The laid eggs form a ribbon covered with mucus. Depending on the type of monkfish, its width ranges from 50 to 90 cm, its length is from 8 to 12 m, and its thickness is from 0.4 to 0.6 cm. These ribbons drift unhindered across the expanses of water. Such peculiar clutches usually consist of 1-3 million eggs, separated from each other and located in mucous hexagonal cells in a single layer. In the European monkfish large caviar, its diameter can be about 0.23-0.4 cm. American anglerfish eggs are smaller in size (only 0.15-0.18 cm in diameter).

After some time, the walls of the cells begin to collapse, and the eggs, thanks to the drops of fat contained in them, do not settle to the bottom, but float freely in the water. After a few days, the anglerfish larvae hatch. Unlike adults, they have a non-flattened body with large pectoral fins. A characteristic feature of their ventral and dorsal fins are highly elongated anterior rays. Hatched monkfish larvae live in the surface layer of water for 15-17 weeks. They feed on small crustaceans carried by water currents, larvae of other fish species, pelagic eggs, etc.

Taken from: fishes.science

Growing up, the larvae undergo metamorphosis: gradually their body shape becomes like that of adults. Having reached a length of 60-80 mm, the fry descend to greater depths. When young individuals grow to a length of 13-20 cm, they inhabit medium depths, but sometimes they can be seen near the shore. In the first year of life, the growth rate of monkfish is very fast, and then it slows down.

Commercial importance of monkfish

Despite its name and peculiar appearance Monkfish is an edible bottom-dwelling fish that has a fairly large commercial value. Environmentalists are even trying to ban its fishing on the European coast, since here angler fish are caught not with fishing rods, but with the help of nets and trawls. The meat of representatives of the genus Lophius has excellent taste qualities and looks like lobster meat. It has almost no bones, it white, dense consistency, but at the same time tender. French and Spanish gourmets consider it a delicacy.

The predator's head is used to prepare delicious rich broths and seafood soups. Boiled monkfish meat is added to various salads, cut into pieces or cubes, it can be grilled or stewed with vegetables. Steamed or baked anglerfish meat in parchment paper in an ideal way suitable for dietary nutrition, since the fat content in it is minimal, and there are no carbohydrates at all in the presence of a large amount of proteins, various minerals, amino acids, as well as vitamins B, E, PP, A and D. In addition, the calorie content of monkfish is only 68.2 kcal.

• Representatives of the genus Lophius are often called not only monkfish, but also “tail fish.” The nickname appeared due to the fact that angler fish in stores usually appear already cleaned and without a head. In fact, only one tail remains on the shelves.
• Sea devil fish are able to masterfully camouflage themselves at the bottom of reservoirs. It’s not just the ability to change body color that helps them become invisible. environment(stones, driftwood, algae), but also its own appearance. The head of the fish, the edges of its jaws and lips, and the skin are overgrown with appendages, hanging fringes and tufts, reminiscent of algae leaves that move in the water.
• Residents of the tropics have many legends about the angler fish, which is terrible in appearance and attacks swimmers. But if we compare the number of people injured by sharks, octopuses or barracudas, then the number of victims from monkfish teeth is quite small. The predator almost never attacks humans, because divers usually do not swim to depths of 700 m or more. Fish can harm scuba divers only when they rise to coastal waters after spawning and are very hungry. At this time, swimmers should not approach, much less stroke, the monkfish, because he may bite your hand.
• The meat and liver of this bottom-dwelling fish are considered a delicacy, so there is a threat of extinction of the genus due to its increased fishing. In England, in the winter of 2007, a decision was made to ban the sale of monkfish in the country's supermarket chains.

Anglerfish, or sea devils (Lophius) are very bright representatives a genus of ray-finned fish belonging to the family of anglerfish and the order of anglerfish. Typical bottom inhabitants are found, as a rule, on a muddy or sandy bottom, sometimes half-burrowing into it. Some individuals settle among algae or between large rock fragments.

Description of monkfish

On two sides of the monkfish’s head, as well as along the edges of the jaws and lips, hangs fringed skin that moves in the water and resembles algae in appearance. Thanks to this structural feature, anglerfish become inconspicuous against the background of the ground.

Appearance

The European anglerfish has a body length of within a couple of meters, but more often - no more than one and a half meters. The maximum weight of an adult is 55.5-57.7 kg. The aquatic inhabitant has a naked body, covered with numerous leathery growths and clearly visible bony tubercles. The body is flattened, compressed towards the back and belly. The eyes of the monkfish are small, widely spaced. The dorsal area is brownish, greenish-brown or reddish in color with dark spots.

The American anglerfish has a body no more than 90-120 cm long, with an average weight of 22.5-22.6 kg. The black-bellied anglerfish is a deep-sea fish reaching a length of 50-100 cm. The body length of the Western Atlantic anglerfish does not exceed 60 cm. The Burmese monkfish, or Cape anglerfish, is characterized by a flattened head huge size and a fairly short tail, which occupies less than a third of the total body length. The size of an adult does not exceed a meter.

This is interesting! The devil is a unique fish in appearance and lifestyle, capable of moving along the bottom with peculiar jumps, which are carried out due to the presence of a strong pectoral fin.

The total body length of the Far Eastern anglerfish is one and a half meters. The aquatic inhabitant has a large and wide flat head. The mouth is very large, with a protruding lower jaw, on which there are one or two rows of teeth. The skin of the monkfish is devoid of scales. The pelvic fins are located in the throat area. Wide pectoral fins are distinguished by the presence of a fleshy blade. The first three rays of the dorsal fin are separate from each other. Top part the body is brown in color, with light spots surrounded by a dark border. The lower part of the body is characterized by a light color.

Character and lifestyle

According to many scientists, the very first anglerfish or monkfish appeared on our planet more than a hundred million years ago. However, despite such a venerable age, the characteristic behavior and lifestyle of the monkfish on this moment not very well studied.

This is interesting! One of the anglerfish's hunting methods is to jump using its fins and then swallow the caught prey.

Such a large predatory fish practically does not attack humans, which is due to the significant depth at which the anglerfish settles. When rising from the depths after spawning, too hungry fish can harm scuba divers. During this period, the monkfish may well bite a person on the hand.

How long do anglerfish live?

The longest recorded lifespan of the American anglerfish is thirty years. The black-bellied anglerfish lives in natural conditions for about twenty years. The lifespan of the Cape monkfish rarely exceeds ten years.

Species of monkfish

The genus Anglerfish includes several species, represented by:

• American anglerfish, or American monkfish (Lophius americanus);
• Black-bellied anglerfish, or southern European anglerfish, or budegassa anglerfish (Lophius budegassa);
• Western Atlantic anglerfish (Lophius gastrophysus);
• Far Eastern monkfish or Far Eastern anglerfish (Lophius litulon);
• European anglerfish, or European monkfish (Lophius piscatorius).

Also known are the South African anglerfish (Lophius vaillanti), the Burmese or Cape anglerfish (Lophius vomerinus) and the extinct Lophius braсhysomus Agassiz.

Range, habitats

The black-bellied anglerfish has become widespread in the eastern Atlantic, from Senegal to the British Isles, as well as in the waters of the Mediterranean and Black Sea. Representatives of the species Western Atlantic anglerfish are found in the western Atlantic Ocean, where such an anglerfish is a bottom-dwelling fish that lives at a depth of 40-700 m.

The American sea devil is an oceanic demersal (bottom-dwelling) fish that lives in the waters of the northwest Atlantic, at a depth of no more than 650-670 m. The species has become widespread along the North American Atlantic coast. In the north of its range, the American anglerfish lives at shallow depths, and in the southern part representatives of this kind sometimes found in coastal waters.

The European anglerfish is common in the waters of the Atlantic Ocean, near the coast of Europe, from Barents Sea and Iceland to the Gulf of Guinea, as well as the Black, North and Baltic Seas. The Far Eastern anglerfish belongs to the inhabitants Sea of ​​Japan, settles at coastline Korea, in the waters of Peter the Great Bay, as well as near the island of Honshu. Part of the population is found in the waters of the Okhotsk and Yellow seas, along the Pacific coast of Japan, in the waters of the East China and South China Seas.

Anglerfish diet

Ambush predators spend a significant part of their time waiting for their prey absolutely motionless, hiding on the bottom and almost completely merging with it. The diet consists mainly of a wide variety of fish and cephalopods, including squid and cuttlefish. Occasionally, sea devil eats all kinds of carrion.

By the nature of their diet, all monkfish are typical predators . The basis of their diet is represented by fish that live in the bottom water column. The stomach contents of anglerfish include gerbils, small stingrays and cod, eels and small sharks, as well as flounder. Closer to the surface, adult aquatic predators are able to hunt mackerel and herring. There are well-known cases when anglerfish attacked not too large birds, which sway peacefully on the waves.

This is interesting! When the mouth opens, a so-called vacuum is formed, in which a stream of water with the prey quickly rushes into the oral cavity of the sea predator.

Thanks to the pronounced natural camouflage, the monkfish, lying motionless on the bottom, is almost invisible. For the purpose of camouflage, an aquatic predator buries itself in the ground or hides in dense thickets seaweed Potential prey is attracted by a special luminous bait, located by monkfish at the end of a kind of fishing rod, represented by an elongated ray of the dorsal front fin. At the moment when crustaceans, invertebrates or fish touch the eski, the lurking sea devil very sharply opens its mouth.

Reproduction and offspring

Fully mature individuals various types become in at different ages. For example, male European anglerfish reach sexual maturity at the age of six years (with a total body length of 50 cm). Females mature only at the age of fourteen, when individuals reach almost a meter in length. European anglerfish spawn at different times. For all northern populations, living near the British Isles, typically spawn between March and May. All southern populations inhabiting the waters near the Iberian Peninsula spawn from January to June.

During the period of active spawning, males and females of the genus of ray-finned fish, belonging to the family of anglerfish and the order of anglerfish, descend to a depth of forty meters to two kilometers. Having descended into the deepest water, the female angler fish begins to spawn, and the males cover it with their milk. Immediately after spawning, hungry, sexually mature females and adult males swim to shallow water areas, where they intensively feed until the onset of the autumn period. Preparation of monkfish for wintering is carried out at a fairly large depth.

The eggs laid by sea fish form a kind of ribbon, abundantly covered with mucous secretions. Depending on the species characteristics of the representatives of the genus, the total width of such a tape varies between 50-90 cm, with a length of eight to twelve meters and a thickness of 4-6 mm. Such ribbons are able to drift unhindered across the expanses of water. A peculiar clutch, as a rule, consists of a couple of million eggs, which are separated from each other and have a single-layer arrangement inside special mucous hexagonal cells.

Over time, the walls of the cells are gradually destroyed, and thanks to the fat drops inside the eggs, their settling to the bottom is prevented and free swimming in water. The difference between hatched larvae and adult individuals is the absence of a flattened body and large pectoral fins.

A characteristic feature of the dorsal fin and pelvic fins represented by strongly elongated anterior rays. Hatched anglerfish larvae remain in the surface layers of water for a couple of weeks. The diet consists of small crustaceans that are carried by water currents, as well as the larvae of other fish and pelagic caviar.

This is interesting! In representatives of the European monkfish species, the caviar is large and its diameter can be 2-4 mm. The eggs laid by the American anglerfish are smaller in size, and their diameter does not exceed 1.5-1.8 mm.

In the process of growth and development, monkfish larvae undergo peculiar metamorphoses, which consist in a gradual change in body shape to the appearance of adults. After the anglerfish fry reach a length of 6.0-8.0 mm, they descend to a considerable depth. Sufficiently grown young individuals actively settle in the middle depths, and in some cases the juveniles move closer to the coastline. During the very first year of life, the rate of growth processes in monkfish is as fast as possible, and then the process of development of the marine inhabitant noticeably slows down.

One of the most interesting inhabitants depths of the sea- This is an angler fish. Repulsive appearance unusual way hunting and relationships with the opposite sex significantly distinguish her from others sea ​​creatures. The habitat of fish at great depths did not immediately make its study possible. Currently, ceratiform or deep-sea anglerfish include a dozen families and more than a hundred known species.

These fish live deep at the bottom

Appearance and varieties

According to one version, the fish's inconspicuous and intimidating appearance, as well as its habitat, gave the fish its nickname, deep-sea monkfish. Some individuals can reach a length of up to two meters. The fish has a disproportionate spherical body, the head occupies more than half of the body. The color helps it camouflage perfectly. Anglerfish are dark brown and black, but their bellies are usually white.

The monkfish's mouth is huge, decorated with a row of sharp, inwardly curved teeth. There may be moving leathery folds around the mouth, which also help the fish to successfully hide in the algae at the bottom and wait for prey.

The fish has no scales, but in some species the bare skin is covered with scales transformed into spines. The anglerfish has very poor vision and sense of smell, and its eyes are very small. A fish raised to the surface looks completely different from what it does at its usual depth. A bloated body and bulging eyes are a consequence of excess internal pressure.

There are 11 families of monkfish

Anglerfish can be divided into 11 families:

• Caulofrines;
• Centrifrines;
• Ceratiaceae;
• Diceratiaceae;
• Long probe;
• Hymantolophaceae;
• Linofrine;
• Melanocetes;
• Novoceratiaceae;
• Oneiridae;
• Thaumatichthaceae.

Another one characteristic feature this type is a fishing rod (illicium). In fact, this is an overgrown dorsal fin, namely the first ray. The species Ceratias holboelli can hide the illicium by drawing it inside the body, while in Galatheathauma axeli it is located directly in the mouth.

In most species, the fishing rod is directed forward and hangs directly towards the mouth, luring in prey. At the end of the illicium there is an esca or bait. The eska is a leather pouch - it is a gland filled with mucus with bioluminescent bacteria, due to which the bait glows. Usually the glow is a series of flashes. Fish can cause and stop glowing, controlling the process by expanding and constricting blood vessels, since the iron needs blood flow, and bioluminescent bacteria need oxygen.

Sexual dimorphism

Sexual dimorphism refers to differences in anatomy between females and males of the same species. This is especially pronounced in anglerfish. For a long time scientists could not understand what a male angler fish looked like because they classified males and females into two different types.

Distinctive feature– there is illusion

The sizes of females vary from 5 cm to 2 meters, and their weight reaches 57 kilograms. These predatory fish have a wide mouth and a highly stretchable stomach. They prey on others deep sea fish. Compared to them, males are simply dwarfs, because they reach a length of no more than 4 cm.

Another difference is the presence of illicium. Only females of this fish have a fishing rod. The deep-sea anglerfish also holds other surprises. Unlike females, males have developed eyes and senses of smell, which they need to find a female.

Habitat and food

The deep-sea anglerfish lives in the waters of the World Ocean. The fish is adapted to live at depths of up to 3 kilometers. The anglerfish is especially common in the Atlantic Ocean, from the coast of Iceland to the Sea of ​​Guinea, preferring cool waters.

Females hunt other deep-sea fish - gonostomidae, chauliodae, melamphae, and also feed on crustaceans and sometimes cephalopods.

The hunting process is as follows. The anglerfish lies on the bottom, hidden in the mud and algae. He turns on the glow of the eski and twitches it so that it looks like the movement of a small fish. To catch prey, the female patiently waits for it to swim to her. It pulls small prey into itself, sucking it in along with the water. It takes a few milliseconds to swallow a curious fish. Sometimes, using its developed pectoral fins or releasing jets of water through its gills, the anglerfish can jump forward, attacking prey.

The anglerfish is an extremely voracious fish; it can attack prey that is three times its size. Although the fish's stomach stretches to impressive sizes, such a meal ends in death for the fish. Since her teeth are curved inward, she cannot spit out her prey and gags.

Monkfish hunting methods are quite extraordinary

There have been cases when a species related to the anglerfish, monkfish, swallowed seabirds with the same outcome. As a rule, the monkfish floats to the top when it eats intensively after spawning. At such moments, he can attack a person.

• Caulofrines;
• Linofrine;
• Ceratiaceae;
• Novoceratiaceae.

Possessing good eyesight and sense of smell, males detect the female by emitted pheromones, which persist for a long time in the still water column. To determine whether a female belongs to their species, males visually evaluate the shape of the fishing rod and the frequency of flashes, which varies among all species. Having made sure that the female is of the same species, the male swims up to her and tightly clings to her side with his teeth.

Having attached itself to the female, the male anglerfish loses its independence. After some time, it fuses with the female’s tongue and lips. Its organs atrophy, in particular, the eyes, teeth, jaws, olfactory organs, fins, and stomach. He becomes one with the female, feeding himself through a system of common blood vessels.

Males find a female easily with the help of pheromones

Reproduction

Like most biological species, the deep-sea anglerfish reproduces in the spring and summer, although no seasonal changes. The ribbon of caviar can reach 10 meters. Millions of fertilized eggs rise to the upper layers of water, to a depth of no more than 30 – 200 meters. There the larvae hatch and for some time are eaten by crustaceans and bristlejaws, accumulating strength before the upcoming metamorphosis.

Larvae of deep-sea anglerfish thrive in warm waters. They can be found in tropical and temperate warm zones ocean, where surface water temperatures can reach 20 degrees.

By the time metamorphosis occurs, the fry descend to a depth of 1 km. Sexually mature anglers descend to their usual depth of habitat - 1500 – 3000 meters. Currents can carry anglerfish even into subarctic and subantarctic waters.

Eating

The European anglerfish or monkfish is a commercial fish species and is even considered a delicacy. In particular large quantities Monkfish is caught in Great Britain and France, but in general it is caught all over the world - in America, Africa, East Asia.

The fish gained its popularity due to its dense, boneless meat, although quite tough. The tail part of the anglerfish is eaten, and soup is made from the head. The tail is prepared in many ways. Monkfish dishes are especially appreciated in France.

In this video you will learn more about this fish:

Monkfish is a predatory fish of the order Anglerfishes. This species received the name “monkfish” because of its very unattractive appearance. The fish is edible. The meat is white, dense, boneless. Monkfish is especially popular in France.

Whatever they call them - sea devils, sea scorpions, angler fish, and European anglerfish. However, there are also several varieties of this miracle fish. And in terms of originality of appearance, each of the types is not inferior to each other. People have never seen devils, but the sea monsters that have risen from the depths resemble creatures from the underworld.

It is worth saying that in the aquatic fauna there is another monkfish - the mollusk, but now we will talk specifically about the representative of ray-finned fish.

In fact, it's simple sea ​​fish- a predator fish with an amazing, unlike anything else appearance. These fish belong to the ray-finned fish, to the order Anglerfishes, to the family Anglerfishes, to the genus Anglerfishes. Now in the watery depths of the earth there are two varieties of monkfish.

Appearance

When you first look at this creature, a remarkable organ immediately catches your eye - the “fishing rod”. The modified fin really resembles a fishing rod with a luminous float. This ugly monster, sometimes reaching up to two meters in length and 30-40 kilograms, can itself regulate the glow of its float. But there is nothing supernatural about this. In fact, the float is a kind of skin formation, in the folds of which amazing bacteria live. In the presence of oxygen, which they draw from the blood of the anglerfish, they glow. But if the monkfish just had lunch and lay down to take a nap, he does not need a glowing flashlight, and it blocks the access of blood to the fin-fishing rod, and the float goes out until the start of a new hunt.

All appearance the monkfish marks him out as an inhabitant of the deep sea. An elongated body, with an unnaturally large head, all covered with some kind of growths, vaguely reminiscent of either algae, or tree bark, or some kind of twigs and snags.

The body length of the monkfish is about 2 meters, and the animal weighs almost 20 kilograms. The body has a slightly flattened shape. In general, the anglerfish is not a very pleasant-looking fish. It is all covered with some kind of leathery growths that look similar to driftwood and algae. The head is disproportionately large, the monkfish's mouth and mouth are huge and unpleasant.

Habitat

The habitat of this fish is considered to be Atlantic Ocean. The anglerfish is found off the coast of Europe, off the coast of Iceland. In addition, monkfish have been found in the waters of the Baltic Sea, Black Sea, North Sea and the Barents Sea.

The depth at which these fish usually live is from 50 to 200 meters. Most often they are found at the very bottom, because there is nothing more pleasant for monkfish than just lying quietly on sand or silt. But it is only at first glance that the angler fish is idle. In fact, this is one of the ways of hunting. The animal freezes, waiting for its prey. And when it swims by, it grabs it and eats it.

Nutrition

Mainly, other, usually smaller, fish serve as food for these fish. The monkfish menu consists of Katrans, Silversides, Kalkans, Stingrays and others.

In general, the monkfish is incredibly voracious and therefore boldly rushes even at a seemingly obviously unattainable goal. And in “hungry” moments the sufferer almost complete absence In sight, a large anglerfish rises to the upper layers of water from the depths and at such moments it is capable of attacking scuba divers. You can meet such an inhabitant of the deep sea just at the end of summer, after a grueling hungry spawning, the “devils” go to shallow water, where they eat intensively until the fall, after which they go to wintering in greater depths.

However, compared to sharks, barracudas and octopuses, true sea devils or anglerfish do not pose an immediate danger to humans. Be that as it may, their terrible teeth can disfigure the hand of an unwary fisherman for life. However, the monkfish causes much more damage not to humans, but to other commercial fish species. Thus, there are legends among fishermen that, having fallen into a fishing net, he ate the fish that got there while he was there.

Reproduction

Male and female anglerfish are so different in appearance and size that until some time experts classified them into different classes. The breeding of monkfish is as special as its appearance and hunting method.

The male anglerfish is several times the size smaller than a female. To fertilize the eggs, he needs to find his chosen one and not lose sight of her. To do this, males simply bite into the female’s body. The structure of the teeth does not allow them to free themselves, and they do not want to.

Over time, the female and male grow together, forming a single organism with common body. Some of the “husband’s” organs and systems atrophy. He no longer needs eyes, fins, or a stomach. Nutrients come through the blood vessels from the “wife’s” body. The male only has to fertilize the eggs at the right moment.

They are usually spawned by the female in the spring. Fertility anglerfish quite high. On average, a female lays up to 1 million eggs. This occurs at depth and looks like a long (up to 10 m) and wide (up to 0.5 m) ribbon. A female can carry several “husbands” on her body so that they fertilize at the right time a large number of caviar.

It should be noted that a female monkfish can simultaneously lay a clutch of about three million eggs. After some time, the eggs are released and travel on their own in sea waters. Turning into larvae, they live closer to the surface of the water for up to four months, and only when they reach a length of 6-8 cm do they sink to the bottom.

Monkfish are not able to compare the feeling of hunger with the size of their prey. There is evidence of an angler catching a fish larger than itself, but being unable to release it due to the structure of its teeth. It happens that a monkfish catches a waterfowl and choke on its feathers, which leads to its death.

Monkfish in cooking

Monkfish is suitable both for frying in pieces and for frying in layers on the grill, or cut into cubes and placed on skewers on the grill. Monkfish is boiled and stewed. The fish is especially popular in France, where the meat of its tail is prepared in many ways, for example with blackcurrant jam or sweet potato, and the head of the devil is used for rich, fatty, multi-spiced soup.

Monkfish meat is highly prized in Japan. Not only meat is eaten, but also liver, fins, skin and stomach.

The Chinese prefer to cook monkfish in a wok. The fillets are fried in oil with rice vinegar and soy sauce, sprinkled with ginger and chili. Then the wok is removed from the heat, the fish is covered with coriander and green onions, stir, serve with rice. Everyone who has tried this dish finds it slightly smoky. It's all a play on spices and the characteristics of the wok. The fish turns out tender and very juicy thanks to quick frying.

In America, monkfish is cooked mainly on the grill. The fish is cut into pieces along with the skin and vertebral bone. Marinate with salt, olive oil and rosemary. The oil envelops the pieces of fish and prevents them from drying out. Monkfish is served with grilled vegetables, seasoned with lemon juice and olive oil.

In America, they prepare carrot puree with monkfish fillet meatballs. The carrots are boiled until soft, then simmered in heavy cream, chopped with the addition of coriander and salt. The monkfish fillet is crushed, mixed with salt and spices, and formed into meatballs the size of Walnut, boil them for a couple. The puree is served in deep plates, with a dozen meatballs placed in each and sprinkled with fresh herbs.

In Korea, the national dish He is made from monkfish and a sweet-spicy soup is cooked, to which they add a lot of vegetables and fried monkfish (fillet) in batter. Monkfish meat, seasoned with hot spices, is placed in rice dough (pancakes) and fried in a large amount of oil. Serve fish with soy sauce.

In gourmet restaurants in a number of countries you can find dishes where monkfish is presented in the following form. The fish is fried and served, doused with sweet and sour sauce, poached fish is served with lemon and lemon zest, as well as poached and served with parsley or spinach sauce with cheese. The fish is fried with chili pepper, smoked paprika and ginger, simmered in white wine, cream sauce, milk, baked with tomatoes, fried, strung on rosemary sprigs.

Monkfish is baked in the form of a roll. The fillet is laid out in a layer on film, the filling is placed on top, for example broccoli, and rolled up. The ends of the film are tied, the roll in this form is lowered into water and the fish is boiled for 10 minutes at a temperature not exceeding 86`C. With this method, the fillet remains soft and juicy, but holds its shape perfectly. Served with fish cream sauce and fried potato medallions.

Monkfish are not often available for free sale, because... already mentioned above, the fish is under state protection and its catch is limited. Unfrozen monkfish can be found in large hypermarkets at a very high price during a certain season or on the market from private sellers (this is in Europe and America). The rest of the time, if fish is sold, it is frozen, but its price is just as high - 20 euros per 1 kg.

It has an extremely unattractive appearance. According to one version, this is why it was named that way. It lives at the bottom, hiding in the sand or between rocks. Feeds on fish and various crustaceans, which it catches using its dorsal fin as a fishing rod with bait dangling in front of its mouth.

Description

Monkfish belongs to the order of anglerfish, the ray-finned family. It is also known as the European anglerfish. It grows up to 1.5 - 2 m in size and can weigh up to 20 kg or more. In catches it is usually found up to 1 m long and weighing up to 10 kg. The body is flattened, disproportionate, the head occupies up to two-thirds of its length. The color of the upper part is spotted, brown with a greenish or reddish tint. The belly is white.

The mouth is wide, with sharp, large teeth curved inwards. The skin is bare, without scales. The eyes are small, vision and sense of smell are poorly developed. The monkfish fish has leathery folds around its mouth that constantly move, like algae, which allows it to hide and camouflage itself in benthic vegetation.

The anterior dorsal fin plays a special role in females. It consists of six rays, three of which are isolated and grow separately. The first of them is directed forward and forms a kind of fishing rod hanging down to the mouth. It has a base, a thin part - “fishing line”, and a leathery luminous bait.

Habitat and species

Monkfish is found in fishermen's catches in many seas. The European anglerfish is common in the Atlantic. Here it lives at depths ranging from 20 to 500 m or more. It can be found in the seas along the coast of Europe, in the waters of the Barents and North Seas.

The Far Eastern variety of monkfish lives off the coast of Japan and Korea. Found in the Okhotsk, Yellow, and South China seas. Usually inhabits depths from 40-50 to 200 m. The American anglerfish in the northern part of the Atlantic lives at shallow depths, and in the southern regions it is more often found in the coastal zone. It can be found at depths of up to 600 m with a wide range of water temperatures (0 - 20 °C).

Juveniles hatched from eggs differ in appearance from adults. At the beginning of life they feed on plankton and live for several months in upper layers water, and upon reaching a length of 7 cm, they change appearance, sink to the bottom, and become predators. Intensive growth continues during the first year of life.

Not long ago, in the depths of the ocean, they were discovered related species monkfish. They were called deep sea anglers. They can withstand enormous water pressure. They live at depths of up to 2000 m.

Nutrition

Monkfish spend a lot of time in ambush. It lies motionless at the bottom, buried in the sand or camouflaged among stones and aquatic vegetation. The “hunt” can take him 10 hours or more. At this time, he actively plays with bait in order to attract a curious victim. The leathery bulb surprisingly accurately copies the movements of a fry or shrimp.

When an interested fish is nearby, the monkfish opens its mouth and sucks in the water along with the victim. This takes only a few milliseconds, so there is practically no chance of escaping from sharp teeth. In special cases, the anglerfish can jump forward, pushing off with its fins, or use the reactivity of a stream of water released through its narrow gill slits.

Most often, the diet of monkfish is dominated by stingrays, eels, gobies, flounders and other bottom fish. He also does not disdain shrimps and crabs. During intense zhora after spawning, it can rise to the upper layers of water and, despite poor eyesight and sense of smell, attack mackerel and herring. Cases of monkfish preying on waterfowl have been reported. It can be dangerous for a person at such moments.

Monkfish: reproduction

Monkfish (see photo above) is not able to compare the feeling of hunger with the size of its prey. There is evidence of an angler catching a fish larger than itself, but being unable to release it due to the structure of its teeth. It happens that a monkfish catches a waterfowl and choke on its feathers, which leads to its death.

Only females have a “fishing rod”. Each species of these fish has a unique bait that is unique to them. It differs not only in shape. Bacteria living in the mucus of the leathery bulb emit light of a certain range. For this they need oxygen.

The anglerfish can adjust the glow. After eating, it temporarily compresses the blood vessels leading to the bait, and thereby reduces the flow of oxygen-enriched blood there. The bacteria stop glowing and the flashlight goes out. There is no need for it temporarily, and the light can attract a larger predator.

Monkfish, although disgusting in appearance, the meat is tasty, and in some regions it is considered a delicacy. The courage and gluttony of this predator give divers and scuba divers cause for concern. It is better to stay away from a hungry anglerfish, especially a large one.
