It turned out that it was indeed a "striped fish", but the common striped fish would change its color as the surrounding environment changed, and this full-body black expert speculated that it may be due to high deformity.
When a prey is lured to swim over, the tortoise will silently only move its eyes to stare at the prey, until it swims into the attack range, and then swallows the prey as fast as lightning (about one hundredth of a second).
It is a ferocious carnivorous fish that travels from the intertidal zone to 90 m deep and generally lives on the ground floor, so it has fins for walking. It is the fastest vertebrate to bite, can reach 0.22 times the bullet launch, and will also be cannibalistic, so it is better to see them farther away.
His body color changes with the environment, and he is an excellent makeup artist, often standing still between the reefs, mimicking into stones, and taking advantage of the opportunity to devour nearby creatures. Carnivorous, mainly small fish and crustaceans, can also swallow food larger than itself.
The fish has antennae similar to those of the trout, and has a bait-like skin at the front, which is used to shake in a figure of 8 shape to lure the fish into the hook, presumably hence the name. The first dorsal fin spines of the shrew have been specialized into "kissing tentacles", slender and long.
The trout has a big appetite, and its stomach is often filled with the skeletons of large fish such as sharks. The stomach of the Johnson's trout can be inflated so that large prey can also be swallowed. With the fin spines on the top of the head as bait, the spines at the front of the dorsal fin are elongated like fishing rods, and there are skin folds protruding from the front end, which looks like bait. Use this bait to shake, lure the prey, and when the prey approaches, it will suddenly bite and catch, and then swallow it in a big mouthful.
