Description: Shell has 3 whorls; chocolate brown with iridescent gold spiral ridges; the inner edge of the empty shell is iridescent blue. The foot regularly discharges a mucous layer on the shell which apparently makes the animal more difficult for predators to grasp (Ref. 312).
It has a shell size of 3 cm (Ref. 312). Occurs in low intertidal to subtidal levels (Ref. 312). Commonly found in rocky areas and kelp beds (Ref. 95344). Omnivorous, feeding on hydroids, detritus and diatoms (Ref. 312).

Members of the order Archaeogastropoda are mostly gonochoric and broadcast spawners. Life cycle: Embryos develop into planktonic trocophore larvae and later into juvenile veligers before becoming fully grown adults.
