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.


Pelagic Organism a plant or animal that inhabits the open sea and the surface of a lake, sea, or ocean—the pelagic zone. Pelagic organisms are contrasted with benthic ones, that is, benthos. They are divided into organisms that passively float on the surface of the water (pleuston) or in its depths (plankton) and organisms that swim (nekton). A ...


The following are the major points of distinction between the benthic and pelagic zones. Types of Organisms The higher regions of the pelagic zone, such as the epipelagic zone, receive an abundance of sunlight, and hence, organisms capable of photosynthesis are found there.


Pelagic zone, ecological realm that includes the entire ocean water column. Of all the inhabited Earth environments, the pelagic zone has the largest volume, 1,370,000,000 cubic kilometres (330,000,000 cubic miles), and the greatest vertical range, 11,000 metres (36,000 feet). Pelagic life is found throughout the water column, although the ...


Accounting for some 330 million cubic miles, the pelagic zone -- the offshore waters of the ocean -- is the world’s most extensive habitat. Although vast reaches of it are, compared to the lively richness of coastal realms, relatively barren, the open ocean plays host to a vast array of wildlife.


Definition of pelagic organisms. When talking about pelagic organisms, we are referring to all those species that inhabit the middle waters of the oceans and seas, or near the surface . . Therefore, it is clear that this type of aquatic living beings limit, and much, contact with areas of great depth.

Pelagic definition, of or relating to the open seas or oceans. See more.


Pelagic fish live in the pelagic zone of ocean or lake waters – being neither close to the bottom nor near the shore – in contrast with demersal fish, which do live on or near the bottom, and reef fish, which are associated with coral reefs.


Anything pelagic has something to do with the ocean, especially the open area far from the shore. Pelagic birds and fish — like tuna, jellyfish, and the Atlantic puffin — live in the open ocean.
