Are Barnacles Plankton Nekton or Benthos

Holoplankton are permanent members, represented by many taxa in the sea. Meroplankton are temporary members, spending only a part of their life cycle in the plankton. They include larvae of anemones, barnacles, crabs and even fish, which later in life will join the nekton or the benthos.

Is a barnacle a benthos?

Epifauna live attached to hard surfaces such as rocks, shells and pilings or directly on the surface of the Bay’s bottom. Epifauna include oysters, sponges, sea squirts, sea stars and barnacles. An oyster reef is an example of an epifaunal benthic community.

What are examples of plankton nekton and benthos?
