Detailed explanation-1: -The oceanic zone is typically defined as the area of the ocean lying beyond the continental shelf (such as the Neritic zone ), but operationally is often referred to as beginning where the water depths drop to below 200 meters (660 feet), seaward from the coast into the open ocean with its Pelagic zone.

Detailed explanation-2: -The pelagic zone, also known as the open ocean, is the area of the ocean outside of coastal areas. Here you will find some of the biggest marine life species. Species here are affected by wave and wind activity, pressure, water temperature and prey.

Detailed explanation-3: -The open ocean lies beyond the continental shelf: extending from the Arctic to the Antarctic, from the surface down to the deepest parts of the ocean, and encompassing the entire water column. On a map it accounts for 64% of the ocean and 45% of the entire Earth.

Detailed explanation-4: -The ocean is generally divided into three zones which are named based on the amount of sunlight they receive: the euphotic, dysphotic, and aphotic zones.

Detailed explanation-5: -The pelagic zone consists of the open ocean habitat that begins at the edge of the continental shelf and extends from the surface to the ocean bottom. This zone is further sub-divided into the photic (sunlight) and disphotic (twilight) zones where most ocean organisms live.
