Anglerfish, also known as the spoonfish, has a fleshy protrusion above the head of the trout, resembling a small lantern, which is formed by the gradual upward extension of the first dorsal fin of the trout. The reason why the small lantern emits light is because it has glandular cells in the lantern that can secrete photons, which emit light by slow chemical oxidation with oxygen under the catalysis of photonase. Many fish in the deep sea have phototropism, so the small lantern becomes a weapon for the trout to lure food.

American biologists have found a strange fish introduction in the deep sea, which has a transparent head and tubular eyes, and is figuratively called the tube-eye fish, and its scientific name is macropinna microstoma. Since the fish was discovered in 1939, biologists now know that the eye is particularly capable of focusing light. However, their shape only gives the fish a tubular line of sight, so the field of view is very narrow.

The frilled shark, also known as the pseudoemoe eel, is the most primitive species of shark, without subspecies differentiation, known as "living fossils". There are six gill fissures on both sides of the body, and the gills are elongated and wrinkled, and cover each other, so they are named the frilled shark. The reason why there are more sharks than other sharks is likely to be because most of them inhabit the deep-sea environment, which has a relatively low oxygen concentration, so more gill fissures are needed for gas exchange.
The sword-snout shark, sometimes referred to as euclidean barramundi, is a very peculiar deep-sea species. The shark is pinkish-white in color, with blue wings and elastic skin. It's one of the rarest species of sharks, and no one understands why it looks like this, and its long nose is a barrier to prey, but maybe it can help detect the presence of prey.
The scientific name of the silver axefish (gasteropelecus sternicla), also known as the silver swallow, is a freshwater fish in the order Lipidoptera, suborder Lipidopterae, Tsactoral Axefish, a freshwater fish. Distributed in the lower and middle basins of the Amazon River in Colombia, Venezuela and Guyana, the silver axefish has a peculiar appearance and beautiful colors, and is abundant in the place of origin, and can also be used as a small edible fish or bait fish for fishing sports, and can also be used as an ornamental fish.
