Nekton - Wikipedia
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.
Nekton – Types, Examples, and Diagram - Science Facts
2023年2月17日 · 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.
Nekton - an overview | ScienceDirect Topics
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.
Difference Between Plankton and Nekton | Definition, …
2017年10月11日 · 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 …
6.13: Aquatic Organisms - Biology LibreTexts
Nekton are aquatic animals that can move on their own by “swimming” through the water. They may live in the photic or aphotic zone. They feed on plankton or other nekton. Examples of nekton include fish and shrimp. Benthos are aquatic organisms that crawl in sediments at the bottom of a body of water. Many are decomposers.
Nekton - an overview | ScienceDirect Topics
The nekton are swimmers able to navigate at will (e.g., Coleoptera, Hemiptera, some Ephemeroptera), whereas plankton are floating organisms whose horizontal movements are largely dependent on water currents.
Nekton - (World Biogeography) - Vocab, Definition, Explanations
Nekton refers to the group of aquatic animals that are capable of swimming freely and independently in the water column, including fish, squid, and marine mammals. Unlike plankton, which drift with currents, nekton can actively navigate and inhabit various aquatic biomes, influencing both ecological dynamics and food webs in these environments.
Organisms that swim freely in the oceans belong to the group called nekton. Nekton move independently of currents and waves. Most nekton are fish but they include mammals, reptiles, birds, and squid. The mobility of nekton allows them to pursue prey and flee from predators.

2015年1月1日 · Nekton refers to mobile organisms which are able to swim or otherwise move independently of all but the strongest water currents; the term usually refers to fishes, shrimps, crabs, and squids, regardless of whether they are slow-moving epibenthic or faster swimming pelagic organisms.
