The rarest fish on earth. Well, very unusual fish

To date, more than 30,000 are known various types marine and freshwater fish. Scientists explore the World Ocean, discovering new species and gaining more knowledge about aquatic organisms already known to them. The most colorful and unique inhabitants of the underwater depths became known not so long ago. Rare fish prefer greater depths or live in coral reefs, which explains the riot of colors and their unusual behavior.

Very little is known about ocean depths ah, so it's impossible to know exactly how many species live on the deep sea floor.

Rare river fish

Fresh water in rivers and lakes has a lower diversity of species, which is explained by difficult living conditions and active human influence. Only in remote regions, where rivers and lakes are inaccessible to humans and are not so studied, are various exotic rare fish found, which are distinguished by their unusual coloring or body shape, which is uncharacteristic for most species.

The category of rare and endangered species today includes most sturgeons, which are found in nature only in North America, in Russia, China, Iran and a number of other countries Southeast Asia. Today, there is active fishing for sturgeon, which has led to the almost complete destruction of most species of this valuable and rare fish.

Beluga – large predator, which feeds mainly on fish.

Rare sturgeons include:

Siberian sturgeon.
Paddlefish.
Stellate sturgeon.

One of the rarest and interesting species The sturgeon is the paddlefish, which lives in the Mississippi, and its subspecies are found in the Yangtze and other Chinese rivers. This fish is characterized by an enlarged nasal appendage, which in large specimens resembles an oar in appearance. The paddlefish is large in size and weighing up to 90 kilograms, and the rostrum, that is, an enlarged paddle-shaped nasal appendage, can account for one third of the entire body length.

Paddlefish are among the oldest fish, as evidenced by fossil records.

The blind cave fish, which lives in the subtropics of Thailand, is extremely interesting. During evolution, this species lost pigmentation and vision, gaining unique ability climb vertical surfaces. This unique skill is necessary for this fish, since it lives mainly in caves and has adapted to fast current underground streams.

The mudskipper is another extremely interesting freshwater fish. The body structure of the mudskipper resembles a cross between a frog and a tadpole. The fish belongs to the goby family and spends most of its life out of water, moving along clayey shores. On land, thanks to the unique structure of its body, the mudskipper can stay for up to half an hour or more.

Mudskippers can be found in mangroves along the coasts of Africa, India, and South Asia.

Exotic sea creatures

The depths of the sea are extremely rich in various exotic and rare species of fish. To date, no more than 20% of the World Ocean has been studied, so new ones are constantly being discovered. deep sea species, which amaze with their appearance, the ability to live in complete darkness and under enormous pressure.

Ambona scorpion

This fish was discovered more than a century ago, but until now scientists have come across only a few specimens, on the basis of which this species was described.

Ambona scorpionfish has the ability to change body color.

TO characteristic features scorpionfish include:

frequent shedding of the keratinized body;
ability to change color;
the presence of specific growths above the eyes;
excellent camouflage abilities.

The Ambona scorpionfish prefers shallow depths and is found near southern coral reefs. Scorpionfish likes to hunt at the very bottom, burrowing into fine sand, luring prey with flexible appendages near the mouth. Ambona scorpionfish prefers exclusively clean warm water, therefore in recent years With the pollution of the World Ocean, the population of this fish has decreased significantly.

Sea sticktail

This is a rare deep-sea fish that has a unique body structure. The stick-tail has a huge mouth in the form of a tubular opening, and its jaws extend into an expanding leather pouch. Such a bag works on the principle of a blacksmith's bellows and is capable of expanding several times, which allows the sticktail to catch and digest prey that is several times its size.

The length of the deep-sea sticktail can reach 10 meters. Moreover, the length of the tail of this fish is 5-6 meters. The tail is extremely hard and long, and its structure has not yet been studied by scientists. This fish was discovered about 20 years ago, and during this time scientists came across only three specimens, which were already dead and in poor condition. But it has still not been possible to capture the behavior of a living sticktail on camera.

Psychedelic toad fish attract attention with their unusual color, which resembles a complex pattern of stripes of white, brown and yellow flowers.

Psychedelic frog

This species of marine fish was discovered in 2009. The frogfish prefers great depths and has an unusual appearance that allows it to camouflage itself against the background of the bottom and corals. The head is large in size, with wide-set eyes. The coloring of the psychedelic frog is extremely interesting- with reddish and yellowish sinuous stripes that extend from the eyes to different sides. The fins of the frog fish are modified and vaguely resemble the paws of land animals. Ichthyologists claim that this species is transitional between aquatic aquatic organisms and terrestrial animals.

Today, several color variations of this rare sea fish are known:

Yellow uniform with turquoise eyes and white lines.
Red variety with yellow stripes.
A dark form that can change color to almost black.

Body color largely depends on the general color range environment. On dark ground and great depth There are black forms, but in shallow water in coral reefs you can simultaneously see yellow and red colors.

The frogfish prefers a bottom lifestyle and is found at depths of about 200−500 meters. Young specimens often stay in shallow water near coral reefs, however, as they mature, they move to greater depths and lead a pronounced predatory lifestyle. It has been established that the habitat of the frogfish is the waters of Australia, as well as the tropical region of the Indian Ocean.

The leaf-like growths of the ragweed are ideal camouflage in its habitat.

Fish rag picker

This species was discovered in 1865, but until now scientists have come across only a few dozen specimens of these fish, which is explained by their secretive lifestyle and strictly limited habitat. This species is notable for the fact that its entire body, fins, tail and head are covered with processes that imitate various algae. Such processes perfectly camouflage ragpickers during their hunt for shrimp and other crustaceans.

The rag picker's habitat is the Indian Ocean and the southeast coast of Australia. The fish leads a hidden lifestyle, prefers clean and warm coastal waters, hiding in corals during the day and going hunting for small plankton and crustaceans at night.

The sunfish is the largest bony fish in the world by mass; average adult fish weigh about 1 ton, and the record specimen caught off Sydney reached a mass of 2235 kg.

Moonfish

This species was discovered back in the 18th century, when this fish was found everywhere. Today, with the pollution of the World Ocean and active fishing, sunfish are becoming less and less common. This species is large in size and has a laterally compressed, tall, short body. Moonfish can reach gigantic size with a body diameter of tens of meters and a weight of up to one and a half tons. Adults feed on jellyfish, eels, squid and various plankton. The moonfish is a poor swimmer, so it does not like strong currents, and often simply lies on the very surface of the water surface.

The thorn is a semi-anadromous fish, as it winters in rivers.

Broad-nosed chimera

The broad-nosed chimera prefers the depths of the Atlantic Ocean, where it feeds on a variety of mollusks. To date, scientists have come across only a few specimens of this extremely rare fish. Its peculiarity is its jelly-like body, which, when raised to the surface, quickly dissolves into the chimera's bony skeleton.

The difficulty of studying this species is explained by its way of life, when the chimera practically does not appear at depths of less than 1000 meters. Only with development special equipment scientists were able to see it in its natural environment at depths of more than one and a half thousand meters.

The frilled shark is a very rare species of shark and looks more like an eel.

Frilled shark

This view deep sea sharks was opened in 1884. In appearance, adult individuals more closely resemble an eel or a strange sea snake. The gill openings, of which there are 6 on each side of the body, are covered with skin folds. Membranes and gill slits are also found in the shark's throat, connecting into a wide leathery blade. This is one of the rarest species of sharks, found only at great depths. To date, the frilled shark has been poorly studied, but in total scientists have come across about 100 specimens of this rare species predator.

Coelacanth lives at depths of up to 100 m or more, length more than 1.8 m, weight up to 90 kg.

Indonesian coelacanth

The Indonesian coelacanth was discovered in 1999. This fish belongs to the coelant family and is the oldest described aquatic organism on earth. Previously, it was believed that all representatives of the coelant order became extinct before the appearance of dinosaurs. Studies have shown that this species appeared approximately 40 million years ago.

To date, no more than a dozen specimens of Indonesian coelacanth have been caught. Coelacanth has a strange body shape with modified lower fins that vaguely resemble the limbs of ancient fossils. The internal structure of coelacanth is extremely unusual - something between the structure of terrestrial animals and classic fish.

European anglerfish lives on the seabed, at a depth of up to 200 meters.

Hairy monkfish

These fish, scary and strange in their behavior, were discovered in 1930. The hairy devil prefers great depths of over 1 kilometer. In such water there is pitch darkness, which is what the devil, who has a luminous appendage on his forehead, takes advantage of. With the help of such a device, the hairy devil attracts crustaceans and other fish, which become victims of this predator.

The method of reproduction of this fish is extremely interesting. Female monkfish measure about a meter and weigh 15-20 kilograms. The male is usually ten times smaller than the females; he simply attaches himself to the body of his chosen one, after which sperm constantly enter the female’s body through the blood. For the rest of his life, the male receives all the nutrients he needs from the huge predator. On one large female you can find several males attached to her at once, which can live like this until their death.

Many people are probably interested in knowing what appearance the most terrible and unusual fish in the world and where they live. This article contains the TOP 10 such marine and freshwater fish. And how once a well-known researcher depths of the sea Jacques Cousteau noted: “If we explored animals on land as we did in the sea, we wouldn’t even find a giraffe; it’s like wandering around with a small flashlight in the dark.” The human mind is disturbed amazing creatures ocean depths, monstrous and beautiful at the same time, most of which are truly amazing.

The mouse fish (pink-lipped pipistrelle), well, very unusual. She has red-pink lips, as if painted on with lipstick. And the body shape is similar to bat. She lives in tropical waters near the Galapagos Islands, and the coast of Costa Rica. Considered a predator. Sometimes it's like unusual look kept in aquariums at home.

The blobfish is undoubtedly one of the most bizarre and unusual ocean creatures. It lives only off the coast of Australia. Its uniqueness lies in the shape of its head, reminiscent of a frowning human face. This is probably the most unusual and funny-looking fish.

The brownie shark (goblin) is the most scary shark(although each shark is scary in its own way). The brownie, or goblin shark, lives all over the world in the seas and oceans, but is very rare. It lives at a depth of up to 1000 meters, but what kind of life it has is not yet known. The jaws of the brownie shark are of interest to collectors.

Coelacanth (coelacanth) is a living reminder of bygone eras. Being, in essence, a reflection of ancient times, it has retained its original features from the prehistoric period. The creepy appearance is complemented by harmless predatory skills. You can meet her in the underwater caves of the Comoros Islands. Powerful scales cover the massive body, protecting the fish’s body like armor. Surprisingly, none of the modern fish have such scales. A significant number of convexities on the outer surface of the scales gives it sawing properties, the value of which becomes quite clear once we remember prehistoric predators. The sharp, large teeth of the massive jaw pose a significant threat to an inattentive victim.

The European sea devil is found off the coast of Europe from the Barents to the Black Sea. The reason for the name was the ugly appearance of these creatures - a huge head with a giant mouth, a body covered with bare skin. The ability to glow on the seabed is based on phosphorescent rays “built into” the body. There is also an additional fishing rod that serves as bait for prey. Habitat of the creepy creature: the Atlantic Ocean.

The viper fish has become widely famous due to its terrifying appearance: a mouth with creepy teeth, a body dotted with luminous points, a photophore on the dorsal fin, which serves as the last beacon for an inexperienced victim. Found in the waters of the Atlantic and Pacific Oceans. Although the size of this terrible and unusual fish is very modest, only 30 - 35 cm.

Stone fish or wartfish is another species that falls under the category of the most terrible and at the same time unusual fish. From the name it immediately becomes clear that this fish looks like a stone and is completely covered with bumps (warts). Wart meat is edible and is used to make the famous sashimi dish. Although the fish itself is considered one of the most poisonous in the world. The dorsal fin has 12 spines which are equipped with poisonous glands.

Belt fish, or herring king. Known by these two names because the unusual, long, laterally flattened body is very similar to a regular belt. And the fish received its second name “herring king” due to its ability to swim with schools of herring. And the dorsal fins, which are located close to the head, form a kind of crown.

Truly deserves the title of the world's thinnest fish. A row of sharp fang-shaped teeth, like those of a predatory animal, is capable of cutting through strong fishing line on a fishing rod. And he doesn’t leave a single chance for his prey. In addition, the Goliath tiger reaches decent sizes of 40, 70, and sometimes even 100 kilograms.

Or Payara is a South American species that is widespread in the Amazon River basin. The "vampire fish" got its name from its two very large fangs. Which help her retain her prey (mostly smaller fish). It is of interest to fishing enthusiasts, because many people want to catch such a scary and unusual trophy.

If you know other scary and unusual fish, post their photos and descriptions in the comments.

Another interesting fact about sabertooths: young fish are so different from adults that it took scientists 50 years to realize that they are the same species.

Witch fish

The witchfish or hagfish is one of the most unusual fish in the world. This is one of the few jawless fish that have survived to this day. It feeds on both small living fish and dead and dying fish - they burrow inside the body and scrape it.

The hagfish also has the dubious reputation of being the slimiest creature on the planet. Pores on both sides of the body secrete a huge amount of viscous, sticky mucus, which predators can choke on. The mucus also acts as a lubricant, which allows the hagfish to climb out of the body of a dead fish into which it has climbed to feast. Moreover, the “witch fish” is the only fish that can sneeze, thanks to which it clears mucus from its only nostril.
It is also the only vertebrate that can curl itself into a knot, allowing it to clear mucus from its body and climb out of fish-like bodies. Hagfish live in the North Atlantic and Mediterranean Sea in large groups, up to 15 thousand in one territory.
The fry are very similar to adult fish, but they have both male and female reproductive organs. As they grow older, they choose their own gender, depending on the demographics of the group.

Black dragon fish

Idiacanth, or black dragon fish, is a long, flexible fish that lives at a depth of about two thousand meters. This fish is an example of extreme sexual dimorphism. Females reach 40 centimeters in length, have small eyes, a chin barbel and long teeth with which they catch other fish. Unlike females, males are only 5 centimeters long, they have no teeth, no chin barbel, and a non-functioning gut. The larval development of the idiacants is amazing - the eyes of the larvae hang on long stalks, which shorten in length as the fish matures, and gradually the eyes reach the eye sockets.

Blobfish: The saddest fish on Earth

The blobfish is unique in its kind, it has a repulsive appearance, and many call it the most disgusting fish found in the sea. This fish lives in deep water, and scientists classify it as a member of the Psycholutidae family. You can meet drop fish in the depths of the Pacific, Atlantic and Indian Oceans. Most often, the drop fish is found off the coast of Australia and Tasmania; it is always found very deep under water - from six hundred to 100 meters. The British call it the toad fish, as well as the Australian goby. The drop fish has a unique body structure, which makes it completely unlike any other fish. The length of the body is up to seventy centimeters; it has no scales or fins. In general, the body of a blob fish resembles a gelatinous mass, the weight of which can be up to 10 kg. This fish has huge eyes, which are often called sad, and a nose shaped like a human. The sad expression on the face of the blob fish is quite understandable, because its interorbital space is wider than the diameter of the eye. Another difference from other fish is expressed in the drop fish by the absence of a swim bladder. It is simply not needed at the depth at which this type of fish lives. It is the gelatinous structure that allows the drop fish to swim, which supports it and helps it not to expend effort in moving in deep water. For the same reason, this fish does not have muscles; it simply swims with the flow, its mouth wide open in anticipation of food falling into it. Drop fish can also wait for their victims, motionless “hanging” in the water. Its main source of nutrition is small invertebrates and plankton. Although, this fish can swallow almost anything that is suitable for food and swims into its mouth. Blob fish under water The body of the blob fish itself produces the gelatinous gel of which it is composed. The air bubble inside the body helps her in this process. The blobfish is an inedible fish, but lately Fishermen in Australia and Tasmania began to increasingly catch it along with other deep-sea prey. Most often, the drop fish is caught in the nets of fishermen who hunt for lobsters. It is because of this that today this species of fish is considered a species that is in danger of complete extinction. What does a drop fish look like on land? The blobfish is difficult to observe in its natural environment, and therefore science cannot provide complete information about it. However, science has managed to uncover one very interesting fact that can make the blob fish more attractive in the eyes of people. This fish is the most caring when it comes to its offspring. Very strange and unusual fact– the drop fish “hatches” its eggs. After the fish has laid eggs, it constantly remains on it for some time, protecting and preserving the offspring. After the offspring of the drop fish are born, she begins to “raise” them. The fry of this fish are never left without parental attention; they are constantly close to their mother. At the same time, the drop fish tries to find the quietest and most hidden places in deep water for the fry, thus diverting danger from them. True, this fish has practically no natural enemies at such depths. Today, the drop fish is one of the most mysterious and incomprehensible creatures on earth. The difficulty in studying it is due to the fact that it lives too deep under water. However, the popularity of this unique fish don't borrow. The Internet is literally teeming with images of this mysterious creature, which is included in the ratings of the most strange creatures on the ground.

Mandarin duck "psychedelic fish" - the most colorful fish in the world

The mandarin duck is perhaps the most colorful and popular fish in the world. Despite its popularity, it is quite difficult to maintain. It feeds exclusively on copepods and can die in captivity due to malnutrition. The mandarin fish, which is also known as the "psychedelic fish", gets its name from its vibrant coloring, which resembles the clothing of the imperial Chinese mandarin.

Goliath tiger fish - the most dangerous freshwater fish

The giant piranha, whose exact name is “Goliath Tiger Fish,” is, in fact, the most dangerous freshwater fish in the world. A total of 5 species are known tiger fish, but the largest species lives exclusively in the Congo River basin. The predator can reach up to 180 centimeters in length and weigh more than 50 kilograms. This monster feeds on various smaller fish, small animals caught in the water, and can also attack humans and even crocodile. Also, the goliath fish is one of the representatives of the unique ichthyofauna of the Congo River, which is not found anywhere else. It is extremely difficult to catch such fish. With its sharp teeth it will bite through fishing line of any thickness, so special steel leads of very high strength are used for this.

Protopter fish can walk and jump

The African protoptera fish has four pairs of thin flagellated fins, with the help of which it vigorously walks along the bottom, gracefully bouncing to accelerate. Moreover, she walks only on her hind “legs”, and to jump she pushes off with all four. Despite the fact that this fish is a lungfish, the protoptera does not walk on bare ground, since the fins are too thin to support its weight. After studying protoptera's walks, scientists suggested that perhaps the earliest creatures learned to walk even before they emerged from the ocean, and that walking fish demonstrate an example of the "emergence of gait" millions of years ago.

Poisonous fish silver locomotive

This fish is called Lagocephalus celeratus, but is best known as the silver locomotive. It usually lives in the tropical zone of the Atlantic and Pacific oceans, but within a few years, thanks to rising temperatures, it reached the Red Sea and began colonizing the Mediterranean. After Greece, Turkey, Israel and Egypt, Italy were warned of its possible appearance, the Messina coast guard announced that local fishermen had caught a poisonous specimen in the strait. The Silver Engine is an extremely poisonous creature. The skin, liver and reproductive organs contain a highly toxic substance, "tetradotossin", which when ingested causes blockage of nerve impulses, causing complete paralysis, respiratory arrest, and subsequent death from suffocation.

The deep sea devil is one of the ugliest animals on the planet.

The Deep Sea Anglerfish looks like a creature from a science fiction world. It may be one of the ugliest animals on our planet and lives in the most inhospitable environment - the lonely, dark seabed. There are more than 200 species monkfish, most of which live in the murky depths of the Atlantic and Antarctic oceans. The monkfish lures its prey with its elongated dorsal spine, curving it around the bait, while the end of the spine glows to attract unsuspecting fish to its mouth and sharp teeth. Their mouth is so large and their body so flexible that they can swallow prey twice their size.

The most strange fish Thaumatikht

Many of us have heard more than once about deep-sea anglerfish, which, with their repulsive appearance, have earned the nickname “ monkfish" But few people know about the monkfish's closest relative, Thaumatichthys pagidostomus, which may well take its place among the most disgusting characters in horror films. These fantastic creatures brought together all the ugliest features that nature has endowed deep sea anglerfish. Unlike its cousins, the thaumatikht hides a glowing bait (called an "esku") in a huge cavernous mouth. The bait mechanism of this deep-sea monster consists of a fishing rod (illicium), which forms the front part dorsal fin and the esky, a glowing gland filled with bioluminescent bacteria. A hungry thaumatikht independently turns on and off the glow of the eski, regulating the supply of oxygen to the vessels. No less surprising is the structure of the mouth of the Thaumatikht - the upper jaw is so large that it can completely cover the lower jaw. All the work of catching and swallowing food is performed by the upper jaw, while the lower jaw is assigned only the function of breathing. The monkfish lies in wait for its prey, hiding deep at the bottom and luring everything that floats past into its mouth-trap. Huge jaws sometimes cause trouble for deep-sea hunters - being greedy by nature, thaumatihts swallow everything that can fit into their voracious mouth. Having grabbed prey that is twice its own size, the anglerfish tries to spit it out, but the structure of its teeth does not allow it to get rid of the unbearable burden, and it suffocates. It’s not for nothing that they say that greed is destructive.

Tripod fish

You will meet everyone at the bottom of the sea: anglerfish, giant squid, fish with huge mouths and other deep-sea “handsome creatures”. Another fish lives next to them - the tripod fish, famous for its three “legs”. “Legs” we called the long bony rays emanating from pectoral fins and tail, the length of which can reach 1 meter. The fish rests on them, sinking to the bottom. All fish from the bathypteroid family (lat. Bathypteroidae), which includes our “long-legged” heroine, are small in size. The length of her body does not exceed 35 centimeters. Unlike the rest deep sea fish they have well-developed eyes, which are located not on the sides of the head, but immediately above the upper jaw. The back of the body is slightly compressed from the sides, and the front, on the contrary, is almost round in cross-section. In the photographs it seems that it is light in color, but it is not. Its true color is dark brown or even black. Bioluminescence, a visible glow, gives it a bluish tint. When the fish “stands” on the bottom, it seems that it is resting on hard and dense rays, but as soon as it starts swimming, they become very flexible and soft. The fish itself regulates the rigidity of its fins, tensing or relaxing them. The tripod fish spends most of its life standing on the seabed and hunting for prey. To do this, it is positioned with the front part of the body against the flow. It opens its large mouth and waits for the current to carry small fish, crustaceans or shrimp into its mouth. So she spends minimum quantity efforts for their food. The most important thing here is patience, patience and more patience. During fishing, by relaxing or straining its long rays, the tripod fish can change the height of its body. Due to this, it can move to where the prey density is greater. Another feature of these fish is hermaphroditism. Each individual has both male and female reproductive organs. This is one of the ways to survive, because at such a depth not every fish is lucky enough to meet an individual of the opposite sex. Tripod fish are found in tropical and warm temperate regions of all oceans, with the exception of the Arctic. They live near the bottom, at depths from 800 to 5000 meters.

The underwater world fascinates with its beauty, and especially with its extraordinary inhabitants of the depths. The most unique and colorful fish became known only recently. Representatives underwater world extremely graceful and original. It is not surprising that contemplation of swimming fish brings a person into a state of peace and tranquility.

Royal Centropyg

This small fish leads a bottom-dwelling lifestyle. Centropyg has a very bright color and looks quite impressive in large aquariums. For the best comfort for the fish, it should have shelters and live rocks overgrown with algae.

Lyrebird angel decorated

This is one of the most beautiful fish, which is started for reef aquarium. The lyrebird angel has an elongated body and a lyre-shaped tail. It has a silver color, and there are wide dark stripes from the back of the head to the tail. They are quite demanding to care for - they require good food and water, as well as a large space.

Royal angelfish

Triggerfish Picasso rectangular

Triggerfish Picasso is a fairly large fish that will decorate an aquarium. The length of its body is about 30 cm. The peculiarity of the fish is that its highly located eyes rotate independently of each other. The triggerfish has enough sharp teeth, so you have to be careful with the fish.

Surgeon blue royal

The Blue Royal Tang is very beautiful due to its bright colors and it also has an attractive body shape. That's enough large fish with a body length of up to 20 cm. Royal blue surgeons mainly prefer plant food.

Six-banded wrasse

The six-banded wrasse is another bright and beautiful representative of the water depths. It is diurnal and can live either alone or with other fish. It got its name thanks to its six bright characteristic stripes. It loves shelter, so the fish needs loose soil in which it burrows. The six-banded wrasse destroys various harmful gastropods.

Tetraodon aquarium helicopter fish

Tetraodon is an original and interesting fish. She swallows water or air and this makes her look like a ball. The length of tetraodon is from 6 to 25 cm. In the aquarium, they always define their territory, live there and do not allow “strangers” to approach them.

Mastacembela

These fish come in both aquarium and large specimens that grow up to two meters in length. They come in different colors - mostly bright tropical shades predominate.

Sea horse

The seahorse is distinguished by its original and interesting unexpected appearance. He looks like a little horse. It moves with its head up, which also distinguishes it from other fish.

Two-tone angel

The bicolor angelfish or centropigus bicolor is a bright and very popular fish of its kind. It can be found in the depths of the Indian and Pacific oceans, as well as in Africa, Indonesia and the waters of the Philippines. As a rule, they live alone or in pairs near the reef or in lagoons. His backside has a rich blue, and the tail, head and front part of the body are bright lemon in color. There is also a bright blue spot on the head.
