1 1 the strangest fish

Spotted fish

Poor poor grouper. In its natural habitat, it looks like a very ordinary fish, living in the depths of the ocean from 3000 to 4000 feet. However, when it is dragged to the surface of the water, its body will swell into a big nose that looks funny-a face that looks very much like a human face.

Marcidus's gelatinous meat has evolved to withstand extreme deep-sea pressure, while allowing the fish to float on the bottom of the sea and ingest organic matter. After being removed from its natural high-pressure environment, spotted fish will swell into a nightmarish substance. I missed it in the blink of an eye, but grouper appeared in the Chinese restaurant scene in Black Man III, which most people thought was a special effect, not a real animal!

Asian sheep head wrasse

The name "wrasse" comes from Cornish, which means "hag" or "old woman". This is the proper name of Asian wrasse Semicossyphus reticulatus. Its face looks like a cartoon exaggerated face of a classic Disney witch, including a prominent chin and forehead. Little is known about Asian sheephead fish, but the oversized face of this fish is probably a feature of sex selection: males (or females) with bigger cups and more knots are more attractive to the opposite sex during mating season. One evidence to support this hypothesis is that the newly hatched Asian sheephead wrasse has an ordinary head.

Yellow box fish

Yellow box fish is equivalent to the ocean of rectangular watermelons they sell in Japan. They often visit coral reefs in the Indian Ocean and the Pacific Ocean and feed on algae and small invertebrates. No one knows exactly why Ostracion cubicus has become a flat and narrow body, which is contrary to the usual evolution trend of Pisces, but its agility in water seems to be more due to its fins than its overall shape. Here are some trivia of pop culture: In 2006, Mercedes-Benz launched a bionic car, which is a "concept car" based on the yellow box fish. If you have never heard of bionic, it may be because this car is a real evolutionary failure compared with its more successful inspiration.

Psychedelic frog

Generally speaking, frog fish is one of the strangest creatures on earth: they have no scales, various appendages and growth, and are often covered by algae. But no frog fish is stranger than the psychedelic frog fish. Histiophrine psychedelic fish found in Indonesian waters in 2009 has a big flat face, beaded blue eyes and a big mouth. The most telling thing is that the striped white orange-brown pattern can probably make it blend in with the surrounding corals. For any potential prey that is not suitable for infatuation, psychedelic frog fish also has a tiny "seduction appendage" on its forehead, which is vaguely similar to a crawling worm.

sunfish

As far as its appearance is concerned, the moon fish is nothing special-if you see it in the aquarium, you may ignore it. In fact, in this list, it is very common next to some other fish. What is really unusual about the moon fish is not its appearance, but its interior: this is the first warm-blooded fish discovered, which means that it can generate its own internal body temperature and keep itself at a temperature 10 degrees Fahrenheit higher than the surrounding water temperature. This unique physiological function gives the moon fish more energy (it is known that it can migrate thousands of miles) and enables it to maintain itself in a challenging deep-sea environment. The convincing question is: If endothermic is such a positive adaptation, why didn't other fish evolve it?

Goblin shark

The goblin shark is equivalent to Ridley Scott's Alien Deep Sea, which is characterized by a long and narrow upper kiss (at the top of the head) and sharp protruding teeth (at the bottom). When the prey is within the range of the prey, Mitsukurina owstoni will forcibly pop out its broken jaw and wrap the prey. (However, don't be too afraid; Demon sharks are extremely lazy and slow, and adrenaline may not be able to surpass a human. M. owstoni seems to be the only living representative of the prosperous shark family in the early Cretaceous 65.438+0.25 billion years ago, which largely explains its unique appearance and eating style.

Atlantic wolf fish

Atlantic wolffish Anarhicas lupus is on the list for two reasons. First of all, this fish is equipped with an incredible pair of wolf-shaped jaws, with sharp front teeth and broken teeth at the back, which is suitable for its hard-shell mollusks and crustaceans. Secondly, what is even more surprising is that lupus lives in such cold Atlantic waters, and it will make its own "antifreeze protein" to prevent blood from clotting at temperatures as low as 30 degrees Fahrenheit. Although this unusual chemical composition makes Atlantic wolf fish unsuitable for food fish, lupus erythematosus is often caught by deep-sea trawl and even endangered.

Red-bellied parrot

Bagu with a red belly seems to be summoned from a nightmare, or at least from a david cronenberg movie. This South American fish has incredible human teeth: the similarities are so close that Pacus will make headlines whenever they are caught outside their usual habitat. Although strange, Pacus with a red belly is called "vegetarian piranha" by some pet shops. The owners of these pet shops often neglect to tell their customers two important facts. Pacus may seriously bite the fingers of careless children, while a three-inch-long baby Pacus may soon exceed the size of its fish tank and need bigger and more expensive accommodation.

Oval ice fish

Almost all vertebrates on the earth use protein hemoglobin (or some variant of it) to carry oxygen, which makes the blood have a characteristic red color. That's not true, filtered ice fish, Chionodraco rastrospinosus. Obviously, the blood in the water sample contains no hemoglobin at all: this Antarctic fish uses any oxygen dissolved directly into the blood from its oversized gills. The advantage of this arrangement is that the blood viscosity of Dendrolimus punctatus is lower and it is easier to be pumped to the whole body. The disadvantage is that cell ice fish must adapt to a relatively low-energy lifestyle, because long-term activities will quickly exhaust its oxygen reserves.

Tooth fish

Vandellia Concertvasa, one of the few parasitic fish in the world, spent almost all her life snuggling in the gills of the larger catfish in the Amazon River. This is unusual in itself, but it is worth adding Vibrio cirrhosis to this list. It is generally believed that it has unhealthy attraction to human urethra and will be painfully parasitic on anyone who is stupid enough to venture into the water. There is only one completely confirmed description about this situation-1997, male, 23 years old. But ... even in this case, the victim's testimony is inconsistent with the forensic evidence. As an investigative doctor later said, the probability of a toothpick fish getting stuck in the urethra is similar to "being struck by lightning and being eaten by a shark at the same time".

Star nanren

A naturalist described it as "the meanest thing in creation", and the stargazing fish was equipped with two big protruding eyes and a huge mouth on its head instead of in front; This fish buries itself at the bottom of the sea, from where it pounces on unsuspecting prey. Was it repelled? Well, that's not all: stargazers also grow two poisonous spines above their dorsal fins, and some species can even give out a slight electric shock. Despite these threatening weapons, stargazing is considered a delicacy in some countries. If you don't mind your dinner staring at you from your plate, and you are sure that the chef has successfully removed the toxic organs, please order it at any time if you find it on the menu.
