Shrimp are swimming, decapod crustaceans classified in the infraorder Caridea, found widely around the world in both fresh and salt water. Adult shrimp are filter feeding benthic animals living close to the bottom. They can live in schools and can swim rapidly backwards. Shrimp are an important food source for larger animals from fish to whales. They have a high resistance to toxins in polluted areas, and may contribute to high toxin levels in their predators. Together with prawns, shrimp are widely caught and farmed for human consumption.

Etymology
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.
Life cycle
Biological
This class contains about half of the crustaceans. The members of this class have a primitive body plan that can be described as shrimp-like, consisting of of a 5-8-7 body plan. They have a small carapace that encloses the head and the thorax, and have a muscular abdomen for swimming. They also have a thin exoskeleton to maintain a light weight. These general characters are common in all members of the class.
The class can be further divided into the Decapods, which are even still divided into the Duedrobanchates (prawns) and the Carideans (shrimp and snapping shrimp).
The prawns have sequentially overlapping body segments (segment one covers the segment two, segment two covers segment three, etc), chlelate (claw like) first three legs, and have a very basic larval body type.
The shrimps also have overlapping segments, however, in a different pattern ( segment two overlaps segments one and three ), only the first two legs are chelate, and they have a more complex larval form.
Biologists distinguish the true shrimp from the true prawn because of the differences in their gill structures. The gill structure is lamellar in shrimp but branching in prawns. The easiest practical way to separate true shrimps from true prawns is to examine the second abdominal segment. The second segment of a shrimp overlaps both the first and the third segment, while the second segment of a prawn overlaps only the third segment.
Commercial and culinary
While in biological terms shrimps and prawns belong to different suborders of Decapoda, they are very similar in appearance. In commercial farming and fisheries, the terms shrimp and prawn are often used interchangeably. However, recent aquaculture literature increasingly uses the term "prawn" only for the freshwater forms of palaemonids and "shrimp" for the marine penaeids.Indian Aquaculture Authority: Shrimp Aquaculture and the Environment - An Environment Impact Assessment Report, ch. 2; IAA report, April 2001.
