Are worms nekton plankton or benthos?

Answer 1

Worms are primarily classified as benthos, as they typically live on or in the sediments of the ocean floor, lakes, and rivers. Some species, like certain marine worms, can also inhabit the water column but are generally not considered nekton or plankton. Nekton refers to free-swimming organisms, while plankton includes organisms that drift with currents. Overall, the majority of worms are adapted to a benthic lifestyle.
