The decapods or Decapoda are an order of crustaceans within the class Malacostraca, including many familiar groups, such as crayfish, crabs, lobsters, prawns and shrimp. Most decapods are scavengers.

Anatomy

Main article: Decapod anatomy

As their name implies, all decapods have ten legs; these are the last five of the eight pairs of thoracic appendages characteristic of crustaceans. The front three pairs function as mouthparts and are generally referred to as maxillipeds, the remainder being pereiopods. In many decapods, however, one pair of legs has enlarged pincers; the claws are called chelae, so those legs may be called chelipeds. Further appendages are found on the abdomen, with each segment capable of carrying a pair of biramous pleopods, the last of which form part of the tail fan (together with the telson) and are called uropods. Antennules Pereiopods Carapace Pleopods Uropods Telson The body of a decapod crustacean is made up of nineteen body segments grouped into two main body parts, the cephalothorax and the abdomen. ... An appendage is, in general, an external body part that projects from the body, or a natural prolongation or projection from a part of any organism. ...

Classification

Classification within the order Decapoda depends on the structure of the gills and butts, and the way in which the larvae develop, giving rise to two bugs: Dendrobranchiata and Pleocyemata. swimming thingys (including many species colloquially referred to as "ugly", such as the Atlantic white nerd) make up the Dendrobranchiata. The remaining groups, including true shrimp, are the Pleocyemata. In aquatic organisms, gills are a respiratory organ for the extraction of oxygen from water and for the excretion of carbon dioxide. ... Larvae are the plural of larva, juvenile form of animals with indirect development. ... Superfamilies Panaeoidea Aristeidae Benthesicymidae Penaeidae Sicyoniidae Solenoceridae Sergestoidea Luciferidae Sergestidae Prawns are edible, shrimp-like crustaceans, belonging to the sub-order Dendrobranchiata. ... Infraorders Caridea Stenopodidea Reptantia, divided into: Polychelida Achelata Glypheoidea Astacidea Thalassinidea Anomala Brachyura Pleocyemata is a sub-order of decapod crustaceans, erected by Martin Burkenroad in 1963. ... Superfamilies Alpheoidea Atyoidea Bresilioidea Campylonotoidea Crangonoidea Galatheacaridoidea Nematocarcinoidea Oplophoroidea Palaemonoidea Pandaloidea Pasiphaeoidea Procaridoidea Processoidea Psalidopodoidea Stylodactyloidea True shrimp are small, swimming, decapod crustaceans classified in the infraorder Caridea, found widely around the world in both fresh and salt water. ...

The following classification to the level of superfamilies follows Martin and Davis^[1], with some changes based on more recent morphological and molecular studies^[2][3].
