Prawn is a common name for large swimming crustaceans, particularly in Britain and Commonwealth nations, and are also called shrimp. Significant commercial species valued for food tend to be large, and thus tend to be called prawns. Shrimp that fall in this category often belong to the suborder Dendrobranchiata. The term is used less frequently in North America, and 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).
Shrimp versus prawn
Shrimp and prawn are common names without the formal definition that scientific terms provide. They are terms of convenience with little circumscriptional significance, and don't represent actual taxa.
According to the crustacean taxonomist Tin-Yam Chan, "The terms shrimp and prawn have no definite reference to any known taxonomic groups. Although the term shrimp is sometimes applied to smaller species, while prawn is more often used for larger forms, there is no clear distinction between both terms and their usage is often confused or even reverse in different countries or regions."
A lot of confusion surrounds the scope of the term shrimp. Part of the confusion originates with the association of smallness. That creates problems with shrimp-like species that are not small. The expression "jumbo shrimp" can be viewed as an oxymoron, a problem that doesn't exist with the commercial designation "jumbo prawns".
The term shrimp originated around the 14th century with the Middle English shrimpe, akin to the Middle Low German schrempen, and meaning to contract or wrinkle; and the Old Norse skorpna, meaning to shrivel up. It is not clear where the term prawn originated, but early forms of the word surfaced in England in the early 15th century as prayne, praine and prane. According to the linguist Anatoly Liberman it is unclear how shrimp, in English, came to be associated with small. "No Germanic language associates the shrimp with its size... The same holds for Romance... it remains unclear in what circumstances the name was applied to the crustacean."
The terms shrimp and prawn originated in Great Britain. Shrimp is applied to smaller species, particularly species that are dorsoventrally depressed (wider than deep) with a shorter rostrum. It is the only term used for species in the family Crangonidae, such as the common shrimp or brown shrimp, Crangon crangon. Prawn is never applied to very small species. It is applied to most of the larger forms, particularly species that are laterally compressed (deeper than wide) and have a long rostrum. However, the terms are not used consistently. For example, some authors refer to Pandalus montagui as an Aesop shrimp while others refer to it as an Aesop prawn.
British Commonwealth countries tend to follow British usage. There are some exceptions in Australia where some authors refer to small species of Palaemonidae as prawns and call Alpheidae pistol shrimp. Other Australian authors have given the name banded coral shrimp to the prawn-like Stenopus hispidus and listed "the Processidae and Atyidae as shrimps, the Hippolytidae, Alpheidae, Pandalidae and Campylonotoidea as prawns". New Zealand broadly follows British usage. A rule of thumb given by some New Zealand authors states; "In common usage, shrimp are small, some three inches or less in length, taken for food by netting, usually from shallow water. Prawn are larger, up to twelve inches long, taken by trapping and trawling." South Africa and the former British colonies in Asia also seem to generally follow British usage.
In the United States the term shrimp is used for almost all species. Prawn is less commonly used. Shrimp is the more general term, both in Britain and in North America, but most particularly in the United States. In the United States, the term prawn applies especially to larger shrimps and those that live in freshwater.
