Like the other species in its family, this worm-like chiton has reduced valves and a large fleshy girdle. It is reddish in colour, usually with large tan bands. Its girdle has a velvety appearance due to the minute spicules that cover it. This species is very similar to Cryptoplax striata, but can be differentiated by the banding and smaller spicules. Juvenile C. striata can be more difficult to tell apart, but they usually have reddish valves.
