Achelata
The Achelata is an infra-order of the decapod crustaceans, holding the spiny lobsters, slipper lobsters and their fossil relatives. ==Description== The name "Achelata" derives from the fact that all the members of this group lack the chelae (claws) that are found on almost all other decapods (from the Greek , ' = "not", , ''chela'' = "claw"). They are further united by the great enlargement of the first antennae, by the special "phyllosoma" form of the larva, and by a number of other characters.
