Angaria nodosa (Reeve, 1842)

Angaria nodosa is the only species in the family Angariidae found in the Marshall Islands. They are found exposed on hard reef, usually on the seaward reef but sometimes on lagoon pinnacles. Their irregular shape and generally heavy encrustations make the shells difficult to see. They are most often seen if they have fallen over and are resting on the bottom aperture up.

Some have much wider nodules, almost fingers, around the periphery of the last whorl.
