In order to better study and understand this huge ecosystem, scientists divide the it into different zones: 1. Imagine the deepest, darkest part of the ocean. The ocean's water column (a conceptual pillar of water measured from the ocean's surface to the seafloor) is often divided into five zonesthe epipelagic, mesopelagic, bathypelagic, abyssopelagic, and hadalpelagic zones. Most of these animals feed on minimal plants and small fish and shrimp. Depths below 6000 m occur within ocean trenches and this is often classified as the Hadal Zone (in both pelagic and benthic divisions). The temperatures of the exploding hot springs can rise over 750 degrees Fahrenheit or 400 degrees Celsius. Hadal zone animals are those that live at extreme ocean depths, between 6,000 and 11,000 m (20,000 and 36,000 ft). You. . At the seafloor, however, abyssal life is concentrated, and the water nearest the seafloor may be oxygen-deficient. There is a wide variety of sea life in these waters where sunlight penetrates. It is the Hadalpelagic . We will discuss this in more detail as we progress through this article. 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. One example is the deep sea anglerfish, which uses a light attached to the end of its head to attract prey, as shown here in this image: Many organisms use bioluminescence, lighting up to attract prey and navigate the darkness. ) or https:// means youve safely connected to the .gov website. 5.

The Abyss (Abyssal Zone) From 13,135 feet to 19,700 feet, the Abyssal zone (aka "the abyss") contains zero sunlight and crushing levels of water pressure. The zones are differentiated based on depth, and each has unique characteristics and unique forms of life that are adapted to conditions in that 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. These animals include fish, shrimp, squid, snipe eels, jellyfish, and zooplankton. The bathypelagic is much larger than the mesopelagic and 15 times the size of the epipelagic. New Zealand Ministry For Culture And Heritage: The Bathypelagic Zone. Most fish that live in the bathyal zone are either black or red in color. The Epipelagic zone is the upper most part of the ocean, lying above the Mesopelagic zone. The region also has a much higher concentration of nutrient salts, such as nitrogen, phosphorus, and silica, as a result of the large amount of dead organic material that drifts down from the above ocean zones and decomposes. The physical characteristics of the seafloor in the Abyssal Biome influence the little life that inhabits or visits the region. Organisms that live in the epipelagic zone may come into contact with the sea surface. The most common squid found in the bathyal zone is the vampire squid, so named for its hunting strategy of descending on prey and draping its tentacles over it like a cloak or net. It lies between the mesopelagic above, and the abyssopelagic below. It is the pitch-black bottom layer of the ocean. What is the Abyssal Zone of the Ocean, AKA Abyssopelagic Zone? environment where an organism lives throughout the year or for shorter periods of time.
