Shrimp
Species
A shrimp seems to be almost any crustacean that isn't a lobster, barnacle, or crab – Greg Jensen A wide variety of non-decapod crustaceans are also commonly referred to as shrimp. This includes the brine shrimp, clam shrimp, fairy shrimp and tadpole shrimp belonging to the branchiopods, the lophogastridan shrimp, opossum shrimp and skeleton shrimp belonging the Malacostraca; and seed shrimp which are ostracods. Many of these species look quite unlike the commercial decapod shrimp that are eaten as seafood. For example, skeleton shrimp have short legs and a slender tail like a scorpion tail, fairy shrimp swim upside down with swimming appendages that look like leaves, and the tiny seed shrimp have bivalved carapaces which they can open or close. Krill resemble miniature shrimp, and are sometimes called "krill shrimp".
