Prawn is a common name, used particularly in Britain and Commonwealth nations, for large swimming crustaceans or shrimp, especially those with commercial significance in the seafood industry. Shrimp that fall in this category often belong to the suborder Dendrobranchiata. In North America, the term is used less frequently, typically for freshwater shrimp. In the United Kingdom prawn is more common on menus than shrimp, while the opposite is the case in the United States. The term prawn also loosely describes any large shrimp, especially those that come 15 (or fewer) to the pound (such as king prawns or jumbo shrimp).
