\nBenthos (or benthic organisms) are the organisms that live on, in, or near the bottom of a body of water, such as an ocean, lake, or river. This category includes a wide range of organisms, from plants like seagrasses to animals like worms, clams, starfish, crustaceans, and even some fish that live on the bottom.
\n<\/section>\n
\n– Benthos are bottom-dwelling aquatic organisms.
\n– They live on the substrate of the water body.
\n<\/section>\n
