Cephalopods, Crustaceans & Other Shellfish, Order Cetacea (whales and dolphins), Family Balaenidae (right whales). 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. Often they have special adaptations to help them reproduce, because finding mates in the dark and sparsely-populated world of the abyssal plain can be a challenging task. It is strongest in the tropics and decrease to non-existent in the polar winter season. The bathyal zone or bathypelagic - from Greek (baths), deep - (also known as midnight zone) is the part of the open ocean that extends from a depth of 1,000 to 4,000 m (3,300 to 13,100 ft) below the ocean surface. In the abyssal zone, life appears ill-adapted to survive in a strange, harsh world. It is the pitch-black bottom layer of the ocean. Since this zone is so deep it is always cold.

These squid can grow up to 43 feet in length and may weigh over a ton, and they have tentacles over 30 feet long, designed to grab elusive prey in the depths of the ocean. These bacteria, for example, convert hydrogen sulfide into sulfate and store the energy from this reaction as chemical energy by synthesizing carbon-based compounds. Dark zone (bathypelagic zone) 4. And then we also must consider that abyssopelagic means open ocean as opposed to the abyssal plain which is the ocean bottom at those depths. As organisms living in these upper layers die, their remains drift toward the ocean floor like soft snow. Animals of the Abyssal Ecosystem | Sciencing The ocean is divided into five zones: the epipelagic zone, or upper open ocean (surface to 650 feet deep); the mesopelagic zone, or middle open ocean (650-3,300 feet deep); the bathypelagic zone, or lower open ocean (3,300-13,000 feet deep); the abyssopelagic zone, or abyss (13,000-20,000 feet deep); and the hadopelagic zone, or deep ocean . Many of these organisms have similar characteristics, such as soft bodies, long lifespans, and long gestation periods.

The Abssal Zone, also known as the Abyssopelagic Zone, is the layer of the ocean that touches the ocean basin, or floor of the ocean. Many abyssal animals are bioluminescent, which means they can produce their own light. A few of the organisms that live in this zone include zooplankton, shrimp, and other small fish. 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. Some organisms can live in this zone by using chemosynthesis, which is energy that is produced by chemical reactions. Animals such as fish, whales, and sharks are found in the oceanic zone. Both have large mouth lined with teeth that are capable of accommodating prey much larger than themselves. The surface of the ocean down to about 200 feet is called the epipelagic zone. She has a Master's Degree in Cellular and Molecular Physiology from Tufts Medical School and a Master's of Teaching from Simmons College.

His articles have appeared in "Plenty," "San Diego Reader," "Santa Barbara Independent" and "East Bay Monthly." What are the conditions like in the abyssal zone? Because of the lack of light, bioluminescence begins to appear on organisms in this zone. Many abyssal animals are bioluminescent, meaning they can produce their own light. Abyssal zone known as the home for many decomposers which feed on bits and pieces of dead stuff that sink down to the bottom. The bathypelagic zone follows from 1000-4,000 m in depth, a subzone containing the infrequent bioluminescent organism. Earth Ocean Formation Theories | How Did the Oceans Form? The life found in the Abyssal Biome is characterized by the extreme environmental conditions that exist at such depths. Some animals that live in the aphotic zone include the gulper eel, giant squid, smaller squids, anglerfish, vampire squid, and numerous jellyfish. It influences animals living here. While the ocean seems vast and unending, it is, in fact, finite; as the climate continues to change, we are learning more about those limits. 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. You will find sharks, tuna, jellyfish, and sea turtles. But the animals of the abyssal plain tend to have special adaptations to help them cope with their unusual environment.
