The Abyssal zone’s average depth is 13,000 feet, but the deepest known point is around 36,000 feet deep. An abyssal zone, also known as an abyssopelagic zone, is the deep part of the ocean below 2000 m. In much of the hydrocarbon resource area of the North West Shelf, the sea bed lies in this depth zone. The zone is home to an astounding range of animals, including many deep-water corals, tube worms, crabs, sponges, sea squirts, and much more. Animals may survive of the remains of other organisms which have fallen to the ocean floor. The bathyal zone and the abyssal and hadal zones below it are referred to as the deep sea. Hadalpelagic -Deep sea trenches are in the hadalpelagic zone. Additionally, mesopelagic marine bacteria also play an important role in global carbon cycling by capturing carbon dioxide and converting it to organic materials, such as proteins and carbohydrates, that can be used to support marine life. The slope, terraces, and plateaux from depths of 200 to 2000 m are referred to as the bathyal or deep-sea zone. In the process, atmospheric carbon obtained by consumed surface animals is transferred to the ocean depths. When dawn arises, the mesopelagic animals retreat back to the cover of the dark mesopelagic zone. Other predators follow zooplankton in search of food creating a vast ocean food web. Many of the mesopelagic animals, like zooplankton, feed on phytoplankton found abundantly in the upper epipelagic zone. Doing so under the cover of dark helps them to avoid daytime predators. These organisms migrate in massive number to the oceans surface at dusk in search of food. With the increasing depth, the carnivores and the scavengers become less abundant than the animals who are. Mesopelagic animals play an important role in the global carbon cycle and ocean's food chain. The abyssal crustaceans and the fish may be blind. These animals include fish, shrimp, squid, snipe eels, jellyfish, and zooplankton. Animals that can withstand the pressures in this depth, which. Here temperature decreases as depth increases toward the abyssal zone, since light cannot penetrate through the deeper water. The very deepest depth of the ocean is roughly 2,000 meters deeper than Mount Everest is tall36,070 feet deep (10,994 m) Each zone has a different mix of species adapted to its specific light level, pressure, temperature, and community. The bottom of the zone consists of sand, slit, and/or dead organisms. There are a number of marine animals that live in the mesopelagic zone. The benthic zone is the area below the pelagic zone, but does not include the very deepest parts of the ocean (see abyssal zone below). The ocean covers 83 of the world’s surface and 60 of the ocean’s area. This zone remains in perpetual darkness at depths of 4,000 to 6,000 meters (13,300 to 20,000 feet). Abyss derives from the Greek word, meaning bottomless. David Shale/Nature Picture Library/Getty Images The Abyssal Zone, or Abyssopelagic Zone, is a layer in the pelagic zone of the ocean. Anglerfish have sharp teeth and a luminescent bulb that is used to attract prey. Anglerfish (Melanocetus murrayi) Mid-Atlantic Ridge, North Atlantic Ocean.
