The abyssal zone is surprisingly made up of many different types of organisms, including microorganisms, crustaceans, molluscan (bivalves, snails, and cephalopods), different classes of fishes, and possibly some animals that have yet to be discovered. Cold: The deep sea has extremely low temperatures. Many animals also move very slowly to conserve energy. The abyssal zone is home to a number of animals such as the deep-sea anglerfish, the black swallower and the giant squid. What is a organism that is adapted to the abyssal zone? The lack of sunlight in this zone also makes it aphotic, so there is no energy being produced from photosynthesis. The ambient temperature is roughly 35-37 degrees Fahrenheit (2-3 degrees Celsius). There is little life found in the Abyssal Biome because it is shaped by its extreme environmental conditions. Why do few organisms live in the abyssal zone? Examples of these adaptations are blindness to semi-blindness due to the lack of light, bioluminescence, and a slow metabolism. Several of these adaptations make residents of the abyss very unique. In order to survive the harshness of the abyssopelagic zone, organisms have grown adaptations to their environment. 52 Which is a biotic factor in a marine ecosystem?
