Ilabitat: commensal in the cloaca and respiratory tree of the holothurian,<br />
Theelothuria princeps (Selenlza), which buries in sand; juvenile crabs are found<br />
in the anterior digestive tract of the host.<br />
Remarks: Wells and Wells (1961) provided data on the natural history,<br />
ecology, and morphology of this crab and Pearce (1966) reviewed the biology<br />
and host relationships. Abele (1970) listed the angel wing mollusc, Cyrtopleura<br />
cosiata, as a host for a sexual intermediate form of this crab. Listed from northwest<br />
Florida by Menzel (1971).<br />
