Main Ref.	Schoppe, S., 2000
Remarks	Inhabits sandy and rubble areas at depths of 0 to 45 m. Feeds on algae and small invertebrates. Associated with Allopontonia iaini, Periclimenes colemani and Leutzenia asthenosomae (commensals) (Ref. 800). Its movement is assisted by non-venomous spines on the underside of its test (Ref. 85384).
