Decapods

A decapod is a crustacean in the large order of Decapoda (from Ancient Greek δεκάς (dekás), meaning "ten", and πούς (poús), meaning "foot"), within the class Malacostraca, including crabs, lobsters, crayfish, shrimp, and prawns. Most decapods are scavengers. The order is estimated to contain nearly 15,000 extant species in around 2,700 genera, with around 3,300 fossil species. Nearly half of these species are crabs, with the shrimp (about 3,000 species) and Anomura including hermit crabs, king crabs, porcelain crabs, squat lobsters (about 2500 species) making up the bulk of the remainder. The

A shrimp (: shrimp (US) or shrimps (UK)) is a common name typically used for crustaceans with an elongated body and a primarily swimming mode of locomotion – usually decapods belonging to the Caridea or Dendrobranchiata, although some crustaceans outside of this order are also referred to as "shrimp".

Astacidea is an infraorder of decapod crustaceans including lobsters (but not "lobsters" such as the spiny lobster etc.), crayfish, and their close relatives.

Pleocyemata is a suborder of decapod crustaceans, erected by Martin Burkenroad in 1963. Burkenroad's classification replaced the earlier sub-orders of Natantia and Reptantia with the monophyletic groups Dendrobranchiata (prawns) and Pleocyemata. Pleocyemata contains all the members of the Reptantia (including crabs, lobsters, crayfish, and others), as well as the Stenopodidea (which contains the so-called "boxer shrimp" or "barber-pole shrimp"), and Caridea, which contains the true shrimp.

genus of crustaceans

Upogebiidae is a family of mud shrimp crustaceans belonging to the infraorder Gebiidea, within the order Decapoda. They are infauna, living their entire adult lives in seafloor burrows. Over 100 species have been identified, with different species often highly specialized for different types of substrate, even including sea sponges or coral. They are filter feeders, although some species also deposit feed.

They do not form a single natural group or clade, but have convergently evolved multiple times from the ancestral decapod body plan through carcinisation, the process of creating this set of characteristic

Laomediidae is a family of mud shrimp crustaceans belonging to the infraorder Gebiidea, within the order Decapoda.

Spongicolidae is a family of glass sponge shrimp in the order Decapoda. There are about 8 genera and more than 40 described species in Spongicolidae. Apart from the shallows-dwelling genus Microprosthema, the family consists of glass sponge infauna (or inquiline), living within the body cavity of their sponge, presumably for life with a few other sponge shrimp. The sponge infaunal species most often inhabit Euplectella sponges, but can be found in Hyalonema sieboldii, Dactylocalyx pumiceus, Regradella phoenix, and R. okinosena.

The remaining seven species are only known from fossils, one belonging to the genus Udorella (the sole member of the family Udorellidae) and the other six belonging to the genus Udora, which cannot yet be assigned to any family.

The entire structure of a decapod crustacean

Natantia (Boas, 1880) is an obsolete taxon of decapod crustaceans, comprising those families that move predominantly by swimming – the shrimp (comprising Caridea and Procarididea), prawns (Dendrobranchiata) and boxer shrimp. The remaining Decapoda were placed in the Reptantia, and consisted of crabs, lobsters and other large animals that move chiefly by walking along the bottom. The division between Natantia and Reptantia was replaced in 1963, when Martin Burkenroad erected the suborder Pleocyemata for those animals that brood their eggs on the pleopods, leaving Dendrobranchiata for the prawns

Reptantia is a clade of decapod crustaceans named in 1880 which includes lobsters, crabs and many other well-known crustaceans.
