\nAquatic organisms are broadly classified based on their mode of life. Plankton are typically microscopic or small organisms that drift passively in the water column. Periphyton are organisms that are attached to submerged surfaces. Benthos are organisms that live on or in the bottom sediments of a body of water. Nekton are actively swimming aquatic animals that can move independently of water currents, such as fish, marine mammals, and large invertebrates. The description “free swimming macroscopic animals” directly matches the definition of nekton.
\n<\/section>\n
\nNekton are actively swimming aquatic animals, distinguishing them from passively drifting plankton, attached periphyton, or bottom-dwelling benthos.
\n<\/section>\n
\nExamples of nekton include most fish species, whales, dolphins, seals, squids, and diving beetles. They occupy various trophic levels within the aquatic ecosystem. The ability to swim actively allows them to seek food, avoid predators, and navigate within their environment.
