Marine research on cumaceans from around the world.

Cumaceans of the World

Cumaceans are small, benthic marine crustaceans, common in muddy and sandy sediments. Most species inhabit the surface layer of the sediments, and are presumed to be deposit feeders, while other species are tube building filter feeders or micropredators. Distribution tends to be patchy, and density can be very high, with cumaceans being among the top 10 most abundant invertebrates in some environments.

The first cumacean was described in 1780, and a second in 1804. Initially, work was slowed by arguments about whether cumaceans were distinct organisms, or larvae of other crustaceans. In 1841, a cumacean brooding eggs was discovered, and the argument resolved.
