About 17 percent of known biological species live in oceans. Marine species are described as either pelagic or benthic. Pelagic organisms live in the water column itself. Benthic species live on the ocean bottom. ... Below the photic zone is the aphotic zone, which is characterized by very limited light (or no light)

Plankton consist of any drifting organisms that inhabit the pelagic zone of oceans, seas, or bodies of fresh water. Plankton are defined by their ecological niche rather than their phylogenetic or taxonomic classification...

Some organisms that are included are the lantern fish and the coelcanth. The coelcanth was once believed to be extinct by many scientists. It was later found in the abyssal zone of the Indian Ocean. Most of the organisms that live in the abyssal zone are only a few millimeters long due to lack of food and sunlight.

1. PELAGIC ZONE ... : "Pelagic" refers to the swimmers and drifters above the bottom; the main subcategories are plankton--organisms at the mercy of currents--and nekton--animals that can outswim currents. Pelagic zones are divided into layers (see Figure above, right):

The benthic zone is the area below the pelagic zone, but does not include the very deepest parts of the ocean (see abyssal zone below). The bottom of the zone consists of sand, slit, and/or dead organisms.

The ocean can be divided into two basic areas: the benthic zone or ocean floor and the pelagic zone or ocean waters. ... It is very cold and completely dark in the midnight zone. Water pressure can be as much as two tons per square inch. Life isn't easy here and this zone has fewer organisms than the other zones.

Out in the open ocean is what is called the pelagic zone, which is host to many species of fish and marine mammals, plankton ,and some floating seaweed. the area underneath the pelagic zone is called the benthic zone, or deep-sea, and is host to silt, sand, and slowly decomposing organisms.
