Caridea

phylum	Arthropoda	The Caridea, commonly known as caridean shrimp, are an infraorder of shrimp within the order Decapoda. They are found widely around the world in both fresh and salt water. In addition to the great variety in habitat, carideans vary greatly in form, from species a few millimetres long when fully grown, to those that grow to over a foot long. Except where secondarily lost, shrimp have one pair of stalked eyes, although they are sometimes covered by the carapace, which protects the cephalothorax.
