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).
