The oyster/pearl oyster lives in the bathypelagic zone of the ocean.
Bathypelagic
Gulper Eels live right in the middle of the Bathypelagic Zone, more commonly known as the "Midnight" Zone, where it is black as night.
-The Epipelagic zone (sunlight zone) -The Mesopelagic zone (twilight zone) -The Bathypelagic zone (midnight zone)
The bathypelagic zone, also known as the midnight zone, extends from a depth of approximately 1,000 meters (3,280 feet) to about 4,000 meters (13,123 feet) in the ocean. In this zone, sunlight does not penetrate, resulting in complete darkness and cold temperatures. It is home to a variety of organisms adapted to high pressure and low light conditions, such as bioluminescent creatures.
Yes, underneath the epipelagic and mythepelagic zones, but over the bottom of the ocean and trenches still farther down than the bottom.
Atolla wyvillei jellyfish are found in most bathypelagic (midnight) zones around the world, between 1000 meters and 4000 meters deep.
Phytoplankton,Seagrass.There are plenty of sea grasses and sea flowers beneath the ocean and other sea plants from which we make several use of things in our daily life such as sponges, and medicines. they are a sort of gift for us from plants under the sea which we get.
Found in tropical-to-temperate waters of the Atlantic, Pacific, and Indian Oceans. Barreleyes inhabit moderate depths, from the mesopelagic to bathypelagic zone, ca. 400-2,500 meters down.
The third layer of the ocean is the Bathypelagic Zone. This is also called the dark zone. There is no sunlight in this zone, and it extends from 1,000 meters to about 4,000 meters in depth. The pressure is extremely high in this zone.
