Many large pelagic fish are oceanic nomadic species that undertake long offshore migrations. They feed on small pelagic forage fish, as well as medium-sized pelagic fish. At times, they follow their schooling prey, and many species form schools themselves. Examples of larger pelagic fish are tuna, billfish, king mackerel, sharks, and large rays.
Diverse pelagic and reef fish species live at the surface when young, [12] including commercially important fish species like the Atlantic cod, salmon, and billfish. Neuston can be concentrated as living islands that completely obscure the sea surface, or scattered into sparse meadows over thousands of miles.
Altogether, 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). [2] [3] [4] Pelagic life decreases as depth increases. The pelagic zone contrasts with the benthic and demersal zones at the bottom of the sea. The benthic zone is the ecological region at the ...

Pacific ladyfish are pelagic, marine forms preferring either brackish or fresh water unless they are breeding. They prefer specific water depths of no more than 8 m (26 ft). Little is known about the ecology of this species, but they are known to be highly carnivorous, feeding on smaller fish and crustaceans. [2]
The garfish is a long and slender fish with a laterally compressed body, and grows to about 50 to 75 cm (20 to 30 in) in length. The jaws are elongated and armed with sharp teeth. The pectoral, dorsal, and anal fins are situated well back on the body and the latter two are similar in appearance. Positioning the fins so far back gives greater ...
