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.
The pelagic zone occupies 1,330 million km 3 (320 million mi 3) with a mean depth of 3.68 km (2.29 mi) and maximum depth of 11 km (6.8 mi). Fish that live in the pelagic zone are called pelagic fish.Pelagic life decreases with increasing depth.he pelagic zone can be contrasted with the benthic and demersal zones at the bottom of the sea. The benthic zone is the ecological region at the very bottom of the sea. It includes the sediment surface and some subsurface layers.
