The Caridea are one of the main groups of true shrimps. They were previously included under the Natantia, but as that is a paraphyletic assemblagfe the term is no longer used. Of the two main shrimp groups, the Caridea are considered to be closer to the crabs and lobsters (Reptantia) than the Dendrobranchiata (sometyimes called prawns, although generally terms like "prawns" and "shimps" are confused).

The fossil record is sparse, with only 57 fossil species known. The earliest of these cannot be assigned to any family, but date from the Early Jurassic and Cretaceous - Wikipedia. In the Solnhofen numerous genera occur, some of which, such as Udora Munster, and Udorella Oppel have exopodites on the thoracic legs, a primitive character suggesting affinity with the Recent family Acanthephyridae. Other Solnhofen genera, in which these exopodites appear to be wanting, are Blaculla,Hefriga and Elder Miinster. The Recent deep-sea genus Oplophorus Milne Edwards (Acanthephyridae) has been identified in the Upper Cretaceous of Westphalia. Some Caridea are found in frosh-water Tertiary deposits, as for example Homelys von Meyer, from the Miocene of Oeningen; but it is impossible to say what relation they bear to recent fresh-water Caridea - Zittel & Eastman 1913 (public domain) - needs revision

Pleocyemata Burkenroad 1963
From the Devonian
Phylogeny: Decapoda : Dendrobranchiata + * : Caridea + (Stenopodidea + Reptantia)
Comments: Crustacean taxonomy has replaced the earlier sub-orders of Natantia and Reptantia with the monophyletic Dendrobranchiata and Pleocyemata. The latter are united by a number of features, including the fertilised eggs are incubated by the female, and remain stuck to the pleopods (swimming legs) until they are ready to hatch (hence the name) - from Wikipedia
Phylogeny: Pleocyemata : Dendrobranchiata + (Reptantia + *)
Characters: phyllobranchiate gills and chelate first and (usually) second pereiopods, but lack chelae on the third pereiopods (Dixon et al. 2003). - CKT.
