Are humans nekton?

Individual organisms that form nektons are generally high on the food chain, ecologically, and some of their main predators are humans. Think of some of the most popular marine life that humans eat — crabs, shrimp and tuna, for instance. These are all examples of organisms that form nektons.

The Nekton and Plankton Communities. 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.

What mainly distinguish nekton from benthos?

What is the difference between Nekton Plankton and Benthos? Nekton live throughout the water column whereas plankton live closer to the water surface. Unlike nekton and planktons, benthos linked to the ocean floor. Some benthos are free living, while others live attached to the seabed.
