Ankang fish is a skin flap based on the first spine of dorsal fin, which is called "bait" biologically. Some Ankang fish that inhabit the dark deep sea also have luminous bait, just like small lanterns on bamboo poles, flickering.

Such bait will never be damaged and does not need to be replaced, which makes other fish mistake it for a bug. Ankang's fishing method is very cunning. It has always maintained a high degree of vigilance, observing the movements around it with its eyes that can rotate at will. Under the temptation of simulated bait, once a small fish is found near the bait, it will open its mouth and suck it into its mouth. Ankang has two rows of fangs lying inward in his mouth. Once bitten by Ankang, a small fish will go to born to die.

Extended data:

First, the cause of the light.

Fish luminescence is a special biochemical reaction caused by enzyme catalysis. Luminous fluorescein is catalyzed by luciferase, which absorbs energy and becomes oxidized fluorescein, releasing photons and emitting light.

This is a special case of chemiluminescence, that is, it only emits light without heating. Some fish can emit white light and blue light, some fish can emit red light, yellow light, green light and ghost light, and some fish can emit several different colors at the same time. For example, a fish in the deep sea has a large luminous cheek organ, which can emit blue light and light red light, while other tiny luminous points in the whole body emit yellow light.

The luminescence of fish has four biological meanings: trapping food, attracting the opposite sex, connecting populations and confusing enemies. This is somewhat similar to the truth that headhunting companies such as Fiberhome headhunters hunt for talents, that is, they use various methods to achieve the success of hunting operations.

Second, the characteristics of pectoral fin of Ankang fish

The pectoral fin is wide and arm-shaped; The ventral fin is small, and the chest position is separated from each other; The trailing edge of the caudal fin is round. The first three spines of dorsal fin are separated. The first spine is located on the back of the snout and has a flap (also known as a cortical nail) at the top. There are some glowing bacteria in the racket, like a bright lamp hanging from a fishing rod. Scales are medium-sized, with scales on the head and gill cover and no lateral lines. Two dorsal fins, not connected; The tail is cylindrical and short. The gluteal fin has 8 ~ 1 1 fin.
