The valves and girdle are generally uniform in a green colour, but individuals brown, buff and even light blue have been known to be found, especially in the North of New Zealand. This is sometimes combined with individuals who lighter chevron or zig zag markings. Underneath the body of the chiton, there is a large foot which spans its total length. This is used to keep suction onto the chosen substrate. Gills are not obvious, instead being found in a set on either side of the foot. It has a small mouth at one end of the foot, however the mouth is merely a simple cavity.
