The Cephalocarida are a class in the subphylum Crustacea comprising only 12 species. Both the nauplii and the adults are benthic.[1] They were discovered in 1955 by Howard L. Sanders,[2] and are commonly referred to as horseshoe shrimp. They have been grouped together with the Remipedia in the Xenocarida. Although a second family, Lightiellidae, is sometimes used, all cephalocaridans are generally considered to belong in just one family: Hutchinsoniellidae. Fossil records of cephalocaridans has been found in 462 million year old deposits.[3]
