The abyssal zone which is also called the abyssopelagic zone is the layer of the pelagic zone of the ocean. These include the epipelagic zone (sunlight zone), mesopelagic zone (twilight zone), bathypelagic zone (midnight zone), abyssopelagic zone (abyssal zone), and the hadalpelagic zone. The pressure in the bathypelagic zone is extreme and at depths of 4,000 meters (13,100 feet), reaches over 5850 pounds per square inch! The lowest form of the food chain would be like phytoplankton and . While there are no plants in the abyssal zone, there are other living organisms that survive here. This puts many of the species that live there in danger and is causing many populations to decline. These animals include fish, shrimp, squid, snipe eels, jellyfish, and zooplankton. The Abyssopelagic Zone (Lower Midnight Zone) was once thought to be bottomless. Other fish attract prey with bioluminescent (light produced by a living organism) lures, including the dragonfish and the angler fish. Abyssal animals do not need to worry about pressure because the pressures within their bodies are the same as that outside. Water depth, temperature, and the presence or absence of light are some of the conditions that differ in these habitats. The Rights Holder for media is the person or group credited.

Appearing here is an image of a dead specimen of a giant squid examined by scientists: Therefore, although the conditions in the abyssal zone may seem frightening, many animals are able to call this ecosystem home and have evolved to survive in this environment. All right, let's take a moment or two to review. You cannot download interactives. He is currently studying for his master's degree. As a result of the frigid temperatures of the ocean water, the animals here have very slow metabolic rates and only eat occasionally sometimes only every few months. The Epipelagic zone is the surface layer of the ocean that extends over 200 meters or 656 feet long. The Abyssal Zone, or Abyssopelagic Zone, is a layer in the pelagic zone of the ocean. These extreme temperatures are quickly surrounded by the colder temperature of the open ocean water. The females have an appendage that is attached to a bioluminescent ball. There are organisms that eat detritus directly, as well as organisms that eat detritus indirectly. This capability is important because the deep sea is completely dark, and the ability to produce light can help fish lure their prey, find prey or attract mates.
