During research in coastal marshes of the Mississippi Delta region in 1975, a large, undescribed amphipod belonging to the genus Cerapus was discovered in tidal channels. This new species, C. benthophilus, is characterized by its large size and 7-12 segmented antennal flagella. Habitat preference is muddy silt bottoms upon which it constructs conspicuous mats or "tufts" of interwoven tubes in shallow coastal bays and marshes from Louisiana to the panhandle areas of northern Florida.
