epifauna because they live on the bottom not within the sediments (infauna)
Benthos is a term for bottom-dwelling (i.e. on, in, or very near) organisms because they live on the seabed (what is known as the "benthic zone"). There are different classifications though: the epifauna live on the sea bottom and infauna live in the sediments on the sea bottom.
Clams
Aquatic animals that live in thesubstrateof a body of water.
Try "infauna"
The prefixes identify what subdivision the fauna falls into for a given place or region; for example avifauna refers to the birds; entomofauna are the insects; epifauna are the animals living on the surface of the seabed or a riverbed, or attached to submerged objects or aquatic animals or plants; ichthyofauna refers to the fish; infauna are the animals living in the sediments of the ocean floor or river or lake beds; megafauna, the large mammals of a particular region, habitat, or geological period; and microfauna are the microscopic animals of a microhabitat.
Some are and some aren't. Infauna just refers to animals that live in the sediments. If they extend feeding appendages out into the water to capture prey (like mud anemones for example) , then they're not deposit feeders. If they remove organic matter from the sediments, they're deposit feeders. Most benthic infauna are deposit feeders.
