Animals that may be found in the abyssal zone include:
Anglerfish: They use bioluminescence to lure in prey with a specialized lure on their head.
Tripod fish (Bathypterois grallator): Their habitat is along the ocean floor, usually around 4,720 m below sea level. They face the current while standing still on their long rays. Once they sense food nearby, they use their large pectoral fins to hit the unsuspecting prey towards their mouth.
Dumbo octopus: This octopus usually lives at a depth between 3,000 to 4,000 meters, deeper than any other known octopus. They use the fins on top of their head, which look like flapping ears, to hover over the sea floor looking for food. They use their arms to help change directions or crawl along the seafloor. To combat the intense pressure of the abyssal zone, this octopus species lost its ink sac during evolution. They also use their strand-like structured suction cups to help detect predators, food, and other aspects of their environment.
Cusk eel (Genus Bassozetus): There are no known fish that live at depths greater than the cusk eel. The depth of the cusk eel habitat can be as great as 8,370 meters below sea level.
Abyssal grenadier: This resident of the abyssal zone is known to live at a depth ranging from 800 and 4,000 meters. It has extremely large eyes, but a small mouth.
