The gumboot chiton is the largest chiton species in the world. It's pretty easy to identify unless you mistake it for a meatloaf! This chiton grows to a maximum length of about 13 inches. Its eight butterfly shaped inner plates are completely covered by a grainy red-brown girdle. It can be found very low in the intertidal on rocky beaches and subtidally to a depth of about 65 feet. It can also be found washed up on the beach, especially after a storm. The grainy texture and red coloration may be worn away in a washed up specimen leaving it a yellow-tan color and resembling half a cantaloupe.

If you find a live chiton, please leave it attached to the rock.   They are not able to reattach themselves very well and will probably not survive if pulled up.
