This notable chiton can grow up to 62mm long and is distinguished by a wide fleshy girdle that is orange in most individuals, sometimes covered in a greenish algal growth. The reduced
valves are sculptured in purple patterns often with white markings, with pustules in lateral areas and five strong radial ribs on the head valve. The ventral underside is orange, a thin film covers the off-white mantle and is easily removed. ==Habitat==
