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 euphotic zone is the portion of the photic zone near the surface where light is strong enough for photosynthesis to occur. In the open ocean, this zone can reach a depth of 100 meters, but the zone will be much shallower close to shore where water clarity is typically reduced.he aphotic part of this zone has giant squid and other species that are adapted to life in deep water. Benthos organisms such as giant kelp, sponges, crabs, sea anemones, sea stars, and marine worms that attach to, crawl upon, or burrow into the seafloor occupy parts of the benthic zone.
