The largest chiton found on SA coasts, Lorica volvox is found in crevices or under rocks, and is usually heavily encrusted. It is a reddish-green in overall colouration, with a red and white striped girdle. When visible, its valves are patterned with a seried of longitudinal serrated ridges in the pleural areas, and scattered nodules in the lateral areas. The rear valve features raised nodules, arranged in radial ridges. Heavily-encrusted specimens can be mistaken for Plaxiphora albida, but that species has a flatter keel, and is usually found on exposed rock.
