* * *Any of several small crustaceans (genus Artemia) inhabiting brine pools and other highly salty inland waters throughout the world.A. salina, which occurs in vast numbers in Great Salt Lake, Utah, is commercially important. Young brine shrimp hatched there from dried eggs are used widely as food for fish and other small animals in aquariums. Up to 0.6 in. (15 mm) long, the brine shrimp's body has a distinguishable head and a slender abdomen. It normally swims upside down, and it feeds primarily on green algae, which it filters from the water with its legs.Brine shrimp (Artemia salina)Douglas P. Wilson
* * *(genus Artemia), any of several small crustaceans of the order Anostraca (class Branchiopoda) inhabiting brine pools and other highly saline inland waters throughout the world. Artemia salina, the species that occurs in vast numbers in Great Salt Lake, Utah, is of commercial importance. Young brine shrimp hatched there from dried eggs are used widely as food for fish and other small animals in aquariums. Measuring up to 15 mm (0.6 inch) in length, the body of the brine shrimp has a discrete head with a nauplius (larval) eye and stalked compound eyes, a thorax bearing a series of leaflike limbs, and a slender abdomen without appendages. Brine shrimp normally swim in an upside down position by rhythmically beating their legs. They feed primarily on green algae, which they filter from the water with their legs.
