Squid, commonly known as stuttering fish, toadfish, sea toad, anglerfish, etc., generally live in tropical and subtropical deep-sea waters, and are bony fish
It is a world fish found in the Atlantic, Pacific and Indian Oceans
Above the head of the trout there is a fleshy protrusion, shaped like 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
The trout has a big appetite, it grows in the depths of the dark sea, its body is pointed backwards into a column, its two eyes are born on the top of its head, a blood basin mouth is as wide as the body, and its stomach is often filled with the skeletons of sharks and other large fish
