__NOTOC__
'Prawns' are
shrimp–like
crustaceans, belonging to the
sub-order 'Dendrobranchiata'
[1].
Prawns are distinguished from the superficially similar shrimp by the
gill structure which is branching in prawns (hence the name, ''dendro''="tree"; ''branchia''="gill"), but is
lamellar in shrimp. The
sister taxon to Dendrobranchiata is
Pleocyemata, which contains all the true
shrimp,
crabs,
lobsters, ''etc.''
In various forms of English, the name "prawn" is often applied to shrimp as well, generally the larger species, such as ''Leander serratus''. In the
United States, according to the
1911 Encyclopedia, the word "prawn" usually indicates a
freshwater shrimp or prawn. In
Middle English, the word "prawn" is recorded as ''prayne'' or ''prane''; no
cognate form can be found in any other
language. It has often been connected to the
Latin ''perna'', a ham-shaped
shellfish, but this is due to an old scholarly error that connected ''perna'' and ''parnocchie'' with prawne-fishes or shrimps. In fact, the
Old Italian ''perna'' and ''pernocchia'' meant a shellfish that yielded nacre, or
mother-of-pearl.
Commercial and culinary use
As used in commercial
farming and
fishery, the terms
shrimp and prawns are generally used interchangeably. In European countries, particularly the
United Kingdom, the word "prawns" is more commonly on menus than the term "shrimp", which is used more often in
North America. The term "prawn" is also loosely used to describe any large shrimp, especially those that come 15 (or fewer) to the pound (also called "jumbo shrimp").
Australia and other
Commonwealth countries follow this European/British use to an even greater extent, using the word "prawn" almost exclusively. (
Paul Hogan's use of the phrase
"I'll slip an extra shrimp on the barbie for you" in a television advertisement was intended to make what he was saying easier for his American audience to understand, and was thus a deliberate distortion of what an Australian would typically say.) In Spain, ''gambas al ajillo'' (translated to prawn pilpil) is a popular dish with both the locals and tourists. Traditionally, ''gambas al ajillo'' and other
tapas are served in earthenware
ramekins or ''cazuelas de barro'' in Spanish.
