The surface of the ocean down to about 200 feet is called the epipelagic zone. Because of the lack of light, bioluminescence begins to appear on organisms in this zone. What kind of animals live in the Abyssopelagic zone? Tube worms living in the deep sea vents are shown here: Fish also exist at these depths. The bathyal zone or bathypelagic - from Greek (baths), deep - (also known as midnight zone) is the part of the open ocean that extends from a depth of 1,000 to 4,000 m (3,300 to 13,100 ft) below the ocean surface.

The animals of the abyssal plain rely on this detritus for their food. The humpback anglerfish ( Melanocetus johnsonii ), for instance, has a large mouth with long teeth, which helps it grab its prey the moment it is in close range. There is little life found in the Abyssal Biome because it is shaped by its extreme environmental conditions. At depths of 3,000 to 6,000 meters (which is approximately 9,800 to 19,700 ft), this zone remains in acute darkness. The habitat contains all an animal needs to survive such as food and shelter.

Generally speaking, this zone reaches from the sea surface down to approximately 200 m (650 feet). Despite the abundance of sea life, this water is completely dark and has extreme pressure. In the abyssal zone, life appears ill-adapted to survive in a strange, harsh world. In the ocean, photosynthesis occurs in the sunlit upper layers. What lives in the abyssopelagic zone? - letshealthify.com height: 60px; The animals of the abyssal plain, however, tend to have some adaptations that help them cope with their unusual environment.
