The Abyssal Zone, or Abyssopelagic Zone, is a layer in the pelagic zone of the ocean. Hadalpelagic Zone Depths below 6000 m occur within ocean trenches and this is often classified as the Hadal Zone (in both pelagic and benthic divisions). The only layer deeper than the abyssal zone is the hadalpelagic zone, which occurs from the seafloor into the deepest trenches, or vertical caverns, in the ocean.

Ocean animals have unique adaptations depending on what ocean habitat they live in. The long, thin bodies of eels are adaptable to the pressures of the bathyal zone. The abyssal zone retains several cubic centimeters of dissolved oxygen per liter because the sparse animal populations do not consume oxygen faster than it is introduced. A .gov Students learn about behavioral and biological animal adaptations, watch a video about the Arctic, and research how specific animals have adapted to this harsh environment. The abyssal zone is so deep that it cannot receive sunlight, so there is no photosynthesis and no plant light. These bacteria are food for large tube worms that also inhabit the vents.

The upper boundary between the abyssal zone and the overlying bathyal zone is conveniently defined as the depth at which the temperature of the water reaches 4C (39F); this depth varies between 1,000 and 3,000 m. Waters deeper than 6,000 m are considered the hadal realm by ecologists. Benthic ecosystems include coral reefs, seagrass beds, and other systems in shallow coastal areas and deep hydrothermal vents, the abyssal plain, and other systems in the deep sea. The surface of the ocean down to about 200 feet is called the epipelagic zone. Most of these animals feed on minimal plants and small fish and shrimp. It is in this zone that most of the visible light exists. Zone of the Epipelagic Zone This is the zone of the ocean that is most exposed to light, and as a result, it has the largest populations of marine life.

Which Animals Live in the Aphotic Zone of the Ocean? - All the Science As organisms living in these upper layers die, their remains drift toward the ocean floor like soft snow. This area does not extend along the ocean floor but exists only in the deepest ocean trenches. The abyssal zone is the deepest layer of the ocean near the seafloor, starting at 13,000 feet and going to about 20,000 feet. Photosynthesis in the ocean takes place in the sunlit upper layers. Answer: There are many layers to the ocean floor but the one where 90% of all ocean life lives is the epipelagic, or euphotic zone. What kind of animals live in the Abyssopelagic zone? Zooplanktons are also found in this zone. Bacteria. What animals live in the abyssopelagic zone? Sunlight does not penetrate the eternal darkness below 1,000 meters (3,280 feet), an area known as the aphotic zone, which includes the midnight zone (or bathypelagic zone) between 1,000 and 4,000 meters (3,280 and 13,123 feet), the abyss (or abyssopelagic zone) between 4,000 and 6,000 meters (13,123 and 19,685 feet), and the hadal zone (or .
