The underside of a red chiton.

Tidepool Tim says,  "Chitons are an impressive animal.  They have 8 rows of plates that run down the back.  These are called "valves" along the outside there is a ring of the plate called a "girdle" - these structures protect the chiton like a shell on a turtle.  We once sold dozens of them to an MIT lab that specialized in studying armored creatures. They are kind of like the marine armadillo of the mollusk world.  Chitons lead a rather sedentary life compared to their cousins the limpets. They are omnivorous eating some algae, but also other benthic creatures like sponges, hydroids, and bryozoans.  Chitons have delightful colors and they mimic the seafloor where they live - oftentimes I overlook them as they blend in with the bright red coralline algae on the rocks. To find a chiton it is best to look on the lower sides or undersides of rocks.  The larger the rock tends to reveal a larger chiton specimen. Chitons live at the low tide line or subtidally. In the winter when we have some huge spring tides (full moon) I go out in the dark with my headlamp and freeze my fingers off trying to fill orders for these invertebrates.  On the Pacific coast, some chitons can be up to 8" long!”
