Amazing ocean fish. The most terrible and unusual fish

The oceans are considered the last great and unexplored regions on Earth...

Today I decided to tell you about ten of the rarest fish that you are unlikely to ever see.

1. One-eyed shark

The name speaks for itself. A very rare albino shark was caught in Mexico, but it was already dead. Scientists believe that this type of shark with birth defects can't for a long time exist in wildlife, since it is very attractive for more strong predators.

2 Frilled Shark

Very rare deep sea shark, living at a depth of 1000 meters. Last time was caught in 2007 in the shallow waters of Japan, but the shark died a few hours after it was transported to the marine park.

3. Coelacanth

The oldest species of fish, considered a living fossil. It is believed that coelacanth acquired its current appearance about 400 million years ago. Fish can weigh up to 80 kg and grow up to 2 meters. During the daytime they live at a depth of 100-400 meters, and at night they rise to a depth of 60 meters.

4. Snakehead

Channa amphibeus is a very rare species and can only be seen in northern Bengal, India. It grows to a maximum of 25 cm (usually 10-15 cm) and is found in waters with a temperature of 25 degrees. During rainy periods, snakeheads may move to flooded rice fields surrounded by forest. Aggressive predators.

5. Pelagic megamouth shark

The largemouth shark feeds on plankton and is distributed throughout the world, but to date only 54 individuals have been discovered. Almost nothing is known about the anatomy and behavior of this shark species.

6. Goblin Shark

This is deep sea sea ​​creature lives on the coasts of Japan, Australia, the USA and South Africa. They usually live at a depth of 200-500 meters, but some individuals have been caught at a depth of 1300 meters. Favorite foods are squid, fish and crabs. A distinctive feature, as you have probably already noticed, long nose.

7. Colossal squid

Looking at the photos colossal squid Japanese horror films come to mind, it looks so infernal. The length of a giant squid can exceed 10 meters and its weight can reach 500 kg. The lifestyle is little studied, since cases of capture are very rare.

We are not talking about those types of animals that consist of the head and neck of a lion, the body of a goat and the tail of a snake. Chimeras – cartilaginous fish, living at a depth of 2500 meters and growing up to 1.5 meters in length.

9. Black Crookshanks

Crookshanks became famous not only for its rarity, but also unique ability swallow fish larger than himself. Its highly elastic stomach allows it to swallow prey 10 times its own weight. It lives at a depth of about 1500 meters and reaches 25 cm in length.

10. Black Lizardfish

This type of fish is really very difficult to find. They live at depths of 1500 to 3000 meters, with a maximum size of 30 cm. Distinctive features is purple-black in color and has a very sharp set of teeth.

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? It is difficult to observe a blob fish 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. Is it true, natural enemies This fish has practically no fish at this depth. 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 Tigerfish- 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. There are 5 known species of 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. 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.

deep sea monkfish(Deep Sea Anglerfish) looks like a creature from a sci-fi 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 the 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 is formed by the front part of the dorsal fin and an eski, a luminous 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

Whomever you meet at the bottom of the sea: angler fish, 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”. We called “legs” the long bony rays emanating from the 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 other 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 fishes are found in tropical and temperate warm areas all oceans, with the exception of the Arctic. They live near the bottom, at depths from 800 to 5000 meters.

Ecology

Today it is open and described about 30 thousand species of fish. Some of them can boast such unusual appearance that it’s hard to believe that these are really fish. Some other representatives of these aquatic vertebrates so rare that very little is known about them.

The most unusual and rare fish often found at great depths (sometimes 300-500 meters underwater) and never rise close to the surface. underwater world still conceals many secrets, many of which we just have to reveal.

The rarest fish

Blind fish climbing on rocks

Found in the subtropical regions of Thailand, the cave fish species Cryptotora thamicola lost during evolution vision and pigmentation. But this is not its only feature. This strange fish has adapted to fast cave currents: it can climb vertical surfaces.

The rough, sticky undersurface of its large fins allows the fish to climb and stay on slippery rocks in conditions fast currents and even climb under waterfalls!

Rare fish of the world

Catfish that lives without water

Quite rare and little-studied fish from the squad Catfish– the only one famous fish, which can live without water. It is enough for her to glide along the wet surface of leaves on the banks of streams and rivers.

This slippery fish is something resembles a worm, she has no eyes, apparently because she spends most of her time underground. Nothing more is known about her.

Sole

Fishes from the squad Flounder(lat. Pleuronectiformes) - representatives of very strange vertebrates. Although they are born as quite ordinary fish, their skull gradually deforms with age, until both eyes are in the same plane. This feature allows the fish to acquire a flat body and skillfully camouflage itself on the seabed.

Fish sea ​​tongues families Cynoglossaceae went even further: they are completely lost pectoral fins and developed a smooth teardrop-shaped body. Many species have an arched mouth.

Rare fish species

Sea devils

Fish monkfish families Thaumatichthaceae boast one of the strangest appearances in the animal kingdom. The upper jaw of these fish is often several times larger than the lower jaw; it is also capable of folding in half, allowing the fish easier to suck prey down the throat. Each member of the family has a luminescent prey lure protruding directly above its mouth.

Long probe from the order of monkfish have very long bait, which can be 10 times longer than the body of the fish itself. It is interesting that all these creatures swim upside down, but none of the scientists can really say why.

Another family of monkfish - Batfish- resemble the offspring of a turtle and a chicken. These fish have adapted to move along the seabed using their fins, which are used as paws.

Thus the fish seem to walk along the sandy bottom, looking for prey.

Mudskipper

One of the most famous fish that has the ability to live out of water – mudskipper. She belongs to the family Bychkov and spends most of his time climbing the clayey banks. On land these fish can move much faster than underwater.

The gill cavities of these fish are able to retain water for a long time. If their body remains wet, fish can breathe through thin skin. Male spinyskippers are very territorial and constantly fight each other for influence.

Rare deep sea fish

Sticktail

Sticktail(lat. Stylephorus chordatus) – rare deep sea fish, which is so unusual that it is the only species of its genus and family. This fish has a very unusual mouth. It has one small tubular opening, and the jaws form an expanding skin pouch that works in the same way as a blacksmith's bellows.

Expanding the bag, the fish forcefully sucks in tiny crustaceans along with the water. At the same time, the eyeballs constantly turn like binoculars, focusing on incredibly small prey.

Tripod sloth

This strange deep-sea fish is one of the few examples of living creatures that prefer not to move much in the body of water and eat like coral polyps, sponges And anemones. It stays in place and feeds on plankton passing by.

Its three fins have long, thin projections, allowing the fish to hold onto the mud of the seabed and remain motionless for several days. The fish begins to move only when necessary, using its two front fins, which help it grab pieces of food and move them to its mouth.

Since fish do not need to hunt for food, tripods practically blind. With this lifestyle they can rarely meet with their relatives, so they are hermaphrodites.

on Earth, and some fish are definitely more unusual and scary than others. Below you will find a list of the TOP 11 most unusual, terrible and amazing fish in the world's oceans, ranging from the laughable blob fish to the nightmarish goblin shark and stargazer.

1. Blobfish

In its natural habitat at ocean depths of 900 to 1200 meters, the blobfish ( Psychrolutes marcidus) looks almost like ordinary fish, but when it reaches the surface, its body expands and the fish turns into a comical creature with big nose. This is because the blobfish's gelatinous flesh evolved to withstand intense deep-sea pressure while allowing it to float on the seafloor. Torn out of your usual environment, the blob fish swells into a real monster. You may not have noticed, but the blob fish appeared in the Chinese restaurant scene in the third movie Men in Black, yet most people thought it was a special computer effect and not a real animal!

2. Asian sheephead wrasse

We know little about these fish, but it is likely that their huge forehead and chin are a sexual characteristic of dominance: males (or perhaps females) with larger head growths are considered more attractive to the opposite sex during mating season (one piece of evidence The support for this hypothesis is that newly hatched Asian sheephead wrasses have normal heads).

3. Cube body

The marine analogue of the rectangular watermelons that are sold in Japan is the cube-shaped fish ( Ostracion cubicus) often visits coral reefs Indian and Pacific oceans, feeding on algae and small fish. No one is sure how or why the cube body was distorted classic fish with flat, narrow bodies, but their maneuverability in the water appears to depend more on their fins than on their body shape. An interesting fact is that in 2006, Mercedes-Benz introduced the Bionic concept car, modeled after a cube-shaped fish (if you've never heard of the Bionic, that's because the car was a true evolutionary failure compared to its more successful inspiration ).

4. Psychedelic frog fish

Discovered in 2009 in Indonesian waters, psychedelic frogfish ( Histiophrine psychedelica) have a large flat face, Blue eyes, a giant mouth and, most importantly, a striped white-orange-brown pattern that supposedly allows it to blend in with the surrounding corals. For any potential prey who is not properly hypnotized, the psychedelic frogfish also possesses a tiny "luring appendage" on its head that resembles a wriggling worm.

5. Redfin opah

In terms of its appearance, the redfin opah ( Lampris guttatus) will surprise few people. You may have seen these fish in large aquariums. What makes the redfin opah a truly unusual fish is not on the outside, but on the inside: it is the first identified species of warm-blooded fish, that is, it is independently capable of maintaining its internal body temperature 10 ° C above the temperature surrounding water. This unique physiology gives the redfin opah greater energy (they are known to migrate thousands of kilometers) and also supports them in extreme deep-sea habitats. The hard question is, if warm-blooded metabolism is a beneficial adaptation, then why are other fish cold-blooded?

6. Goblin Shark

Deep-sea analogue of Alien from film director Ridley Scott, goblin shark ( Mitsukurina owstoni) is characterized by a long, narrow snout on the top of the head and sharp, protruding teeth on the bottom. When this shark is within range of its prey, it pushes out its lower jaws and captures the prey. However, do not be afraid, the goblin shark is unusually lazy and relatively slow and would probably not be able to outrun a frightened person. Surprisingly Mitsukurina owstoni is probably the only living shark that flourished during the early 125 million years ago, which explains the fearsome appearance and method of feeding.

7. Striped catfish

Striped catfish ( Anarhicas lupus) made this list for two reasons. Firstly, this fish has a pair of extraordinary terrible jaws, with sharp incisors in front and chewing teeth at the back, which are ideal for and. Secondly, and more astonishingly, the striped catfish lives in such icy Atlantic waters that it is forced to produce its own "antifreeze proteins" that prevent the blood from freezing at temperatures of -1° C. As you might expect, this strange chemical component makes the striped catfish unsuitable as food for humans, but they are so often caught in deep-sea trawl nets that they are endangered.

8. Red pacu

Red pacu ( Piaractus brachypomus) looks like something out of a nightmare, or at least a mutant from a David Cronenberg film: this South American fish has unusual human-like teeth. Oddly enough, red pacu are sold as "vegetarian piranhas" in some pet stores, whose owners often neglect to inform their customers that these fish are capable of inflicting serious, crushing bites on the fingers of their owners, and a 10-centimeter young pacu can quickly outgrow the size of its aquarium. demanding large and expensive dwellings.

9. Spiny-nosed Whiteblood

Almost all animals on Earth use the protein hemoglobin to carry oxygen, which gives blood its characteristic red color. But the spiny-nosed whiteblood ( Chionodraco rastrospinosus) fully lives up to its name, since due to the lack of hemoglobin, its blood is colorless. This amazing Antarctic fish uses whatever oxygen dissolves in its blood directly from its oversized gills. The advantage of this adaptation is that clear blood is less viscous and is more easily pumped throughout the body; The disadvantage is that the spiny-nosed whiteblood must lead a sedentary lifestyle, since prolonged bursts of activity quickly deplete oxygen reserves.

10. Common Vandellia

Described by one naturalist as “the most complex creature in creation,” the stargazer fish has two large, bulging eyes and one huge mouth on top, rather than in front, of its head. The Stargazer burrows into the ocean floor, from where it pounces on unsuspecting victims. Well, that's not all the weirdness: these scary fish two are also growing poisonous thorn above the dorsal fins, and some species can even generate mild electrical shocks. Surprisingly, stargazers are considered a delicacy in Asian countries. If you don't mind having your dinner staring back at you from your plate, and you're confident the chef has successfully removed its toxic organs, don't hesitate to order a meal from Stargazer on your next trip to Asia.

Among the variety of fish living in the oceans, seas, rivers and lakes, as well as in aquariums, there are very expensive and rare species, which cost a lot of money.

Fugu fish (price 100-500$)

Fugu, also called ball fish, is considered by culinary experts to be one of the most dangerous fish to eat. Only trained culinary masters are allowed to cut it using a special technology, only then does it become available to fans of extreme restaurant food and exotic dishes. Due to the complexity of preparation, a small portion of this fish can cost up to $500. It’s no wonder that the Japanese consider this delicacy the most expensive in their country.

Goldfish(price 1.5 $ thousand)

No one would refuse to own a goldfish, even if it costs a lot of money. In the reservoirs of the South Korean island of Cheyu there are fish with scales that have a stunning golden tint. But the price of this treasure reaches 1.5 thousand dollars. Quite cool!

Albino Beluga (price: $2.5 thousand)

The beautiful caviar of the albino beluga fish is appreciated everywhere. Speaking of the most expensive fish ah in the world, it is worth noting what makes them highly rated. One can say about the albino beluga due to the fact that it spawns only once a century. Its weight can reach one ton. And for 100 grams of her caviar you will have to pay 2.5 thousand dollars. A luxurious delicacy!

Arowana (price 80$ thousand)

Beautiful aquarium fish Arowana, also called dragon fish, is highly prized by fish collectors and admirers of unique sea inhabitants. According to legend, the owner of such a fish is guaranteed happiness. These fish, classified as the oldest species, can be seen in aquariums decorating the offices of the world's largest corporations.

Tuna weighing 108 kilograms (price $178 thousand)

The tuna, unique in size, is called a record holder - because of its price paid by the buyer. Large tuna are not a rare catch for fishermen. Soon a new record was set at an auction in Tokyo.

Tuna weighing 200 kilograms (price: $230 thousand)

Another record holder was also sold in Tokyo. The tuna, which weighs almost twice as much, was valued at $230,000. This became a record for the year 2000 of this auction.

Russian sturgeon (price: $289 thousand)

The most expensive of the Russian sturgeons is recognized to be a specimen caught back in 1924 by local fishermen in the Tikhaya Sosna River. The sturgeon “pulled” 1.227 tons, while it produced 245 kilograms of caviar. It is for this excellent quality caviar that sturgeon is considered one of the world's most valuable fish. At today's auction, that sturgeon would fetch no less than $289,000.

Platinum Arowana (price: $400 thousand)

The unique mutant fish, called the platinum arowana, stands out from the dragon fish family with its unique coloring. The owner of this phenomenon, living in Singapore, categorically does not agree to part with his pet, despite the big money offered.

Tuna weighing 269 kilograms (price $730 thousand)

The record holder for tuna is a specimen that was caught and sold in 2012. Because of its weight and its price—it sold for $730,000—it is considered the largest and most expensive tuna in history. And it was also sold at the Tokyo market.

Bluefin tuna weighing 222 kilograms (price: $1.76 million)

The champion's podium among the most expensive fish is occupied by bluefin tuna, which weighed 222 kilograms, for which the buyer paid over $1.5 million. He also broke his own earlier record for purchasing heavyweight tuna. A small piece of this record-breaking tuna costs 20 euros.
