Pelagic fishes could be classified as being coastal and oceanic fishes, depending on the deepness of the water they live in. The coastal pelagic fish dwell in sunlit waters as much as about 655 ft deep, usually on top of the continental shelf. Some of the species consist of forage fish like anchovies, sardines, shad, or even menhaden along with the predatory fish that consume them. An oceanic pelagic fish mostly inhabit waters underneath the continental shelf. Examples can include larger sized fish like the swordfish, tuna, mackerel, as well as the sharks.
Pelagic fish obtain their name from the areas which they live in known as the pelagic zone. Generally the pelagic zone is the biggest habitat on this planet with a volume around 330 million cubic miles. Various species of the pelagic fish can be found all over this zone. Statistics and distributions differ regionally and also vertically, depending on the availability of brightness, nutrients, dissolved oxygen, the temperature, salinity, and the pressure.
