Nekton

the division of the pelagic population that comprises the free-swimming animals. Nekton are capable of withstanding the force of the ocean current and are able to travel over long distances. Fish, squids, cetaceans, pinnipeds, sea snakes, turtles, and penguins constitute the nekton group. A streamlined body shape and a well-developed locomotory apparatus are characteristic of nekton.

In complete contrast to the nekton are the plankton, which are helplessly carried by the ocean currents. The micronekton, represented by animals capable of limited active locomotion, occupy an intermediate position between the plankton and nekton. The micronekton include fry and small species of fish and squids, the larger members of the suborder Natantia, and the euphausiids.
