Cephalocarida is a class inside the subphylum Crustacea that comprises only twelve shrimp-like benthic species. They were discovered in 1955 by , and are commonly referred to as horseshoe shrimps. 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. Even though there is no fossil record of cephalocaridans, most specialists believe them to be primitive among crustaceans. [more]
At least 5 species and subspecies belong to the Family Hutchinsoniellidae.
