The water along the bottom of this zone is actually devoid of oxygen, making it a death trap for organisms unable to return to the oxygen-rich water above. Extreme Adaptation: Surviving in the Hadal Zone | Features Extreme Adaptation: Surviving in the Hadal Zone Posted On March 26, 2019 The ocean is divided into multiple depth zones; epipelagic (0-200m) mesopelagic (200-1000m), bathyal (1000-4000m), abyssal (4000-6000m) and the hadal (>6000m) zone. Animals of the midnight zone include anglerfish and gulper eels. One of their primary benefits is their ability to reconfigure their mission on the fly if they encounter unexpected issues. Name three features of aquatic environments that differ from terrestrial environments. Polar areas, especially the Antarctic, are home to abyssal waters originating at the air-sea interface. WebWe scientists like to categorise things and the ocean depths are no exception. 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. Organisms in the abyssal zone rely on the natural processes of higher ocean layers. The water is pitch black, and the only light visible is bioluminescence. Studying these organisms can help us better understand adaptation to extreme environments. While there are a number of different fish species representing many different groups and classes, like Actinopterygii or ray-finned fish, there are no known members of the class Chondrichthyes, animals such as sharks, rays, and chimaeras, that make the abyssal zone their primary or constant habitat.
