Deep sea dragonfish live in the sea floor 1524 meters deep. There, the visible light from the sky has been absorbed in the middle zone, and the deep zone forms a very dark environment.

Once the prey is attracted close enough by the "bait", it A 'Angler' swallowed with his powerful jaws.
What's unusual about this deep-sea fish is that the male and female are much smaller and look different. The male of this species has only one finger long and small hooked teeth, which can be used to attach them to the female. Once attached, the male's blood circulation system is connected with the female's, and it will spend the rest of its life as a parasite. All the nutrition of 'he' will get caries from 'she'. If the male cannot find a female to attach to, then it will starve to death. For this reason, these males don't care whether other females have husbands. It's important to find a wife first.

The biggest difference between the black giant mouth fish and other kinds of giant mouth fish is that they also have a pair of luminaries under their eyes, which can act as searchlights when searching for prey in the deep ocean.
