True shrimp are swimming, decapod crustaceans classified in the infraorder Caridea, found widely around the world in both fresh and salt water. Together with prawns, they are widely caught and farmed for human consumption. As with other seafood, shrimp is high in calcium and protein but low in food energy. Recipes using shrimp form part of the cuisine of many cultures: examples include shrimp kebabs, shrimp creole, shrimp gumbo, pan fried, deep fried, stir fried.
A shrimp is a shrimp; a prawn is, well, a shrimp. The two words are used interchangeably in markets and restaurants everywhere. The textbooks may agree that a shrimp is a shrimp, but many people (and quite a few cookbooks) refer to this most popular of shellfish as a prawn.
