Protandrous hermaphrodite, changing to female at about 2 to 3 years. Consumes algae, and large individuals defend themselves by clamping down their shell edges on the predators. Commensal flatworm Notoplana patellarum lives in the gill cavity under the shell. Harvested for food in the Transkei (Eastern Cape).[3]
