Most benthos feed on food as it floats by or scavenge for food on the ocean floor. The decomposers can be found in all biological zones of a lake, although they are the dominant forms in the lower hypolimnion where there is an abundance of dead organic matter. Thus, they serve the hunger needs for the bottom feeders, aquatic animals like the crabs and snails, tunicates, and other benthic animals. Find out information about profundal zone. Abyssal life, on the other hand, is concentrated at the seabed, and the water closest to the seafloor may be completely deprived of oxygen as a result. The oxygen consumption of some profundal and other muddwelling animals was studied in relation to varying periods of starvation, varying temperatures and varying oxygen content of the water to find that this oxygen uptake corresponds to moderately active, not to a basal, metabolism. This is the portion of water that receives sunlight. Abyssal Creatures are Old One monstrosities that come from the Abyss, a chaotic world of primordial darkness where chaos reigns supreme.
