![]() We do no realize it, but the abyssal zone covers 60% of the earth and 83% of the oceans. In addition to that, the salinity of the water in the abyssal zone range between 34. Moreover, since the depth oh this biome is extremely deep, the temperature varies from 0 to 4 degrees Celsius. It is incredible how certain organisms are able to survive in this depth, since this amount of pressure would crush a human immediately. Therefore, animals must be able to withstand up to 11,000 psi. It is written that, “Because water pressure increases one atmosphere every 33 feet in depth, animals in the abyssal zone must be able to withstand tremendous amounts of pressure. At the same time, in a location this deep, the pressure is unbearable to humans. Therefore, this zone is filled with complete and perpetual darkness. In this depth, sunlight is unable to penetrate through. It is located under the bathyal zone and above the hadal zone. The abyssal zone itself is located between 20 meters underneath the ocean surface. The word “abyss” is taken from a Greek word, which means “bottomless sea”. Initially, the abyssal zone and the living organisms inside it, suffers the extreme conditions. Conversely, certain organisms have managed to keep their survival in this very biome through particular processes. With a depth reaching down to 6000 meters, it is impossible to inhabit this biome. This unbelievable and incredible biome is called the abyssal zone. ![]() 2 Located deeper than 2000 meters underneath the ocean surface, lies a biome that we have barely seen and realize.
