Generally speaking, this zone reaches from the sea surface down to approximately 200 m (650 feet). Where deep, wide trenches occur in the otherwise flat seafloor, the open water that fills them is the hadopelagic zone. Ocean Habitats and Animal Adaptations - National Geographic Society Above it lies the mesopelagic zone, while below is the abyssal or abyssopelagic zone. Animals adapt to their environments to help them survive. Scientists believe that this lure attracts other fish for its food or mating. It also has incredible pressure, up to 600 times that of the surface. Many species that live in the open ocean (or pelagic realm) truly live in an ocean universe. Animals living in the bathypelagic zone or deeper never see sunlight.1 Some organisms living there, such as vampire squid and humpback anglerfish, produce their own light.2, 4.

Grenadiers, the Most Abundant Deep-Sea Fish. These bacteria, for example, convert hydrogen sulfide into sulfate and store the energy from this reaction as chemical energy by synthesizing carbon-based compounds. Abyssal life includes chemosynthetic bacteria, tubeworms, and small fish that are dark in color or transparent. Bathypelagic Zone region between the high and low tide of an area. The aphotic zone is broken into two levels: the bathypelagic zone and the abyssopelagic zone. Marine algae play a vital role in the ocean's food chain and they produce part of the world's oxygen that reaches the atmosphere.
