Members of the superfamily Paguroidea are better known as the hermit crabs, which are not true crabs but belong to the infraorder Anomura. Paguroid larvae go through several earlier zoeal stages then metamorphose into a decapodid stage (equivalent to the megalopa of brachyuran crabs), before settling to a benthic lifestyle as juveniles.
