A bottom feeder is an aquatic animal that feeds on or near the bottom of a body of water. The body of water could be the ocean, a lake, a river, or an aquarium. Bottom feeder is a general term which is used particularly in the context of aquariums. Biologists often use the term benthos, particularly for bottom feeding invertebrates, such as shellfish, crabs, crayfish, sea anemones, starfish, snails, bristleworms and sea cucumbers. However the term benthos includes all aquatic life that lives on or near the bottom, which means it also includes non-animals, such as plants and algae.
Biologists also use specific terms that refer to bottom feeding fish, such as demersal fish, groundfish, benthic fish and benthopelagic fish. Examples of bottom feeding fish species groups are flatfish (halibut, flounder, plaice, sole), eels, cod, haddock, bass, grouper, carp, bream (snapper) and some species of catfish and shark.

Famous quotes containing the word bottom:
“At bottom there is in Joyce a profound hatred for humanity—the scholar’s hatred. One realizes that he has the neurotic’s fear of entering the living world, the world of men and women in which he is powerless to function. He is in revolt not against institutions, but against mankind.... Ulysses is like a vomit spilled by a delicate child whose stomach has been overloaded with sweetmeats.”
—Henry Miller (1891–1980)
