The chitons are another relatively small group, with around 600 species placed in three Orders. They are flattened, elongated animals with eight overlapping dorsal shell plates or "valves," bordered by a thick "girdle" formed from the mantle. The mantle cavity encloses the foot, with which chitons cling to rocky surfaces. Between foot and mantle on each side of the body is a row of gills.

A chiton can roll itself up into a ball, exposing only the hard shell, when it feels threatened. It moves using an oval, footlike appendage. The chiton also uses the foot to cling to rocks. Chitons feeds upon seaweed and algae.
