Chaetodermatidae

Chaetodermatidae is a family of molluscs belonging to the order Caudofoveata.

Falcidens is one of three genera within the family Chaetodermatida; its radula consists of a single row of teeth which are mineralized in crystalline hydroxyapatite (a most unusual mineral in organisms), and its teeth are not periodically shed and replaced like in other molluscs. For details of the radula, see Radula#In caudofoveates.
