True shrimp are small, swimming, decapod crustaceans classified in the infraorder Caridea, found widely around the world in both fresh and salt water.

Taxonomy
A number of more or less unrelated crustaceans also have the word "shrimp" in their common name. Examples are the mantis shrimp and the opposum or mysid shrimp, both of which belong to the same class (Malacostraca) as the true shrimp, but constitute two different orders within it, the Stomatopoda and the Mysidacea. Triops longicaudatus or Triops cancriformis are also popular animals in freshwater aquaria, and are often called shrimp, although they belong instead to the Notostraca, a quite unrelated group.
Shrimp are distinguished from the superficially similar prawns by the structure of the gills, and by the fact that female shrimp (as in all other pleocyemates) brood the eggs on their pleopods. There is, however, much confusion between the two, especially among non-specialists, and many shrimp are called "prawns" and many prawns are called "shrimp". This is particularly widespread in culinary contexts, including the following sections.
Shrimp as food

Preparing shrimp for consumption usually involves removing the shell, tail, and "sand vein" (a euphemism for digestive tract). Removing the "vein" can be referred to as "de-veining," and it is interesting to note that shrimp do not have any veins; they have an open circulatory system. As with other seafood, shrimp is high in calcium, protein and low in food energy.
Shrimp preparation
To deshell the shrimp, first hold onto the tail while gently removing the shell around the body. The tail can be detached completely at this point, or left attached for presentation purposes. The "vein" is then removed; make a shallow cut lengthwise down the outer curve of the shrimp's body. Pick out the dark ribbon-like vein running lengthwise along the shrimp's back with a pointed utensil. Then rinse the shrimp under cold running water. If the tail has been detached, the vein can be pinched at the tail end and pulled out completely with the fingers. Care with live shrimp is necessary, as they can inflict extremely painful injuries.
Shrimps in aquaria
Image:DSCN8033 1.sized.jpgSeveral types of shrimp are kept in home aquaria and are useful in controlling algae and removing debris. Freshwater shrimp available for aquaria include the Japanese marsh shrimp (Caridina japonica, also called "Amano shrimp," as their use in aquaria was pioneered by Takashi Amano) and ghost or glass shrimps (Palaeomonetes sp.). Popular saltwater shrimp include the cleaner shrimp Lysmata amboinensis, the Fire shrimp (Lysmata debelius) and the Harlequin shrimp (Hymenocera picta).
Taxonomy note
The shrimp genus Physetocaris, previously given its own superfamily (Physetocaridoidea) and family (Physetocarididae), is now merged with family Pandalidae.
