Pelagic Zone. that part of a lake, sea, or ocean that is the habitat of pelagic organismsâplankton, necton, and pleuston.The pelagic zone is opposed to the benthic zone, that is, the bottom of the body of water, which is inhabited by benthos.In oceans and seas, the pelagic zone is divided horizontally into two regions: the neritic (water above the shelf) and the oceanic (all the remaining water).elagic Zone. that part of a lake, sea, or ocean that is the habitat of pelagic organismsâplankton, necton, and pleuston.
In a cool climate (outside the ocean), the temperature can be below freezing, but in a really warm climate, this zone can have warm waters. The pelagic zone: -- This zone is generally a warm zone, however, because warm and cold currents are constantly mixing, it can be cold in some parts and cooler in others.The benthic zone: -- The temperature of this zone is colder than the pelagic zone and is pretty much always cold.The abyssal zone: -- This zone is the coldest of all of the zones.Because no sunlight reaches this zone the water is never heated.n a cool climate (outside the ocean), the temperature can be below freezing, but in a really warm climate, this zone can have warm waters.
