The Processidae are a family of shrimp, comprising 65 species in five genera,{{cite journal |journal = Raffles Bulletin of Zoology |year=2009 |volume = Suppl. 21 |pages=1–109 |title = A classification of living and fossil genera of decapod crustaceans |author1=Sammy De Grave |author2=N.

The first pereiopods are usually asymmetrical, with a claw on one, but not the other (Ambidexter forming the exception to this rule). The rostrum is generally a simple projection from the front of the carapace, with two teeth, one at the tip, and one further back.{{cite journal |journal=Smithsonian Contributions to Zoology |volume=89 |pages=1–41 |first=Raymond B. |last=Manning |author-link=Raymond B.
