Secrets of the depths: Unexplored inhabitants of the world’s oceans

Another amazing inhabitant of the ocean depths is the angler fish. Its distinctive feature is a luminous “fishing rod” used to lure prey in complete darkness. This bioluminescence phenomenon is common to many deep-sea species and serves not only for hunting, but also for communication and protection from predators.

Microbial communities living in hydrothermal vents on the ocean floor are also of great interest to scientists. These organisms live in conditions of high temperature and pressure, receiving energy not from the sun, but from chemical reactions. Studying these communities could shed light on possible life forms on other planets.
