The Stenopodidea is a small group of decapod crustaceans. Often confused with shrimp or prawns, they are neither, but belong in a group closer to the reptant decapods, such as lobsters and crabs. They may be easily recognised by their third pereiopod (walking leg), which is greatly enlarged.[1] In the lobsters and crabs, it is the first pereiopod that is much bigger than the others. There are 71 extant species currently recognised, divided into 12 genera.[1] Three fossil species are also recognised, each belonging to a separate genus.[2][3] The earliest fossil assigned to the Stenopodidea is Devonostenopus pennsylvaniensis from the Devonian.[3] Until D. pennsylvaniensis was discovered, the oldest known member of the group was Jilinicaris chinensis from the Late Cretaceous.[4]
