Those living on the surface of the ocean floor are known as epifauna.

The sled is mostly used to collect epifauna, however some infauna can be gathered as well.

Many gastropods, crabs, and bivalve species are typical of epifauna.

It was composed of Mg calcite and its habitat included the upper-level epifauna.

These feather stars were stationary intermediate-level organisms feeding on suspension epifauna.

These arthropods were a low-level epifauna, fast-moving and detritivore.

Macrofauna may be divided into epifauna (living on the surface and not borrowing) and infauna (those burrowing in sediment).

Mangroves and other estuarine epifauna dominate the boundaries, with the geology composed mostly of marine and stream sediments.

Others fed mostly on epifauna (invertebrates on top of the seafloor surface, also called epibenthos), or alternatively on infauna (invertebrates that burrow into the seafloor substrate).

This species shares its benthic habitat with the similar winter skate; the little skate focuses more on epifauna (organisms living atop the substrate) while the winter skate eats more infauna (burrowing organisms).
