benthic

Of the depths

Benthic describes the ecological zone at the bottom of a body of water—ocean floor, lake bed, river bottom.

Benthic organisms live in or on this substrate: crabs, clams, bottom-feeding fish, worms burrowing in sediment.

Benthic communities are sensitive indicators of water quality.

The term appears in marine biology and environmental science.
