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.
1 Depth & Location The Ocean Pelagic Zone reaches down to a depth of 11 km (6.8 mi) at the lowest point and has an average (mean) depth of about 3.68 km (2.29 mi).2  The depth plays an important role: As depth increases, the abundance of life decreases. 9. 2  Temperature & Pressure The temperature in the Pelagic Zone varies greatly depending on the depth, with the Epipelagic Zone reaching up to 26Â°C and the Bathypelagic Zone falling to temperatures as low as 2Â°C. 3  Because of the depth and water, pressure increases by great amounts in each zone.
