17 Φεβ 2023 · Nektons are marine organisms that can swim and move independently of moving water. Apart from some mollusks and crustaceans, most nektons are vertebrates. Some examples of nektonic organisms are whales, fish, reptiles, and birds. They live at all depths of the ocean. Most live closer to the surface due to the presence of food.
A nekton is a group of marine or lake organisms that swim together in groups and are powerful swimmers in general that can typically swim independently against the current.
Nekton (or swimmers) are living organisms that are able to swim and move independently of currents. Nekton are heterotrophic and have a large size range, with familiar examples such as fish, squid, octopus, sharks, and marine mammals.
Examples of extant nektons include most fish (especially pelagic fish like tuna and sharks), marine mammals (cetaceans, sirenias and pinnipeds) and reptiles (specifically sea turtles), penguins, coleoid cephalopods (squids and cuttlefish) and several species of decapod crustaceans (specifically prawns, shrimps and krills).

ecological overview of nekton from two major zones of the Bay (open water and shore) and another overview focusing on ichthyoplankton. Open water nekton include those species that typically are found in the deepwater areas of the Bay, either in pelagic or demersal habitats, and those that are typically captured with a trawl.
