Nekton or necton (from the Ancient Greek: νηκτόν, romanized: nekton, lit. 'to swim') is any aquatic organism that can actively and persistently propel itself through a water column (i.e. swimming) without touching the bottom.

Feb 17, 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.

nekton, the assemblage of pelagic animals that swim freely, independent of water motion or wind. Only three phyla are represented by adult forms.

Oct 11, 2017 · Plankton and nekton are two types of marine aquatic organisms. The main difference between plankton and nekton is that plankton are passive swimmers that are carried by the water currents whereas nekton are actively-swimming organisms that swim against the …

Nekton refers to living organisms in the Earth's water bodies that can swim independently of currents, such as fish, squid, octopus, sharks, and marine mammals. They are typically found in the water column but can also live close to the ocean floor.

Nov 21, 2023 · A nekton is a group of water or marine organisms that travel together freely. These organisms can be fish, crustaceans or mollusks that live in an ocean or a lake.

Nekton are aquatic animals that swim or move freely in the water. Their movement is generally not controlled by waves and currents. Nekton include fish, squid, marine mammals, and marine reptiles. They live in the sea, lakes, rivers, ponds, and other bodies of water.

Animals that swim or move freely in the ocean are nekton. Nekton come in all shapes and sizes. They live in shallow and deep ocean waters. Most nekton eat zooplankton, other nektons or they scavenge for waste.

A growing body of evidence suggests that most marine nekton (free swimming animals) have well-defined migration behaviors in the sea, potentially defined by specific physical features or, alternatively, migration corridors that are fixed in space.

Nekton generally refers to free-swimming organisms including invertebrates, fi sh, and marine turtles and mammals. In estuaries, however, this term typically refers to fi shes and decapod crusta-ceans. Nekton is a critical functional component of estuarine ecosystems.
