Gumboot Chiton: More Information

Description: Gumboot chitons are low-profile, saggy-loaf-shaped lumps that grow as long as a grown man’s foot.  The entire back is covered by a pebbly/bumpy skin that is brownish-red.  This pebbly/bumpy skin completely covers the eight over-lapping plates that form the back of the chiton; sometimes low bumps show where the plates are.

Sometimes dubbed “butterfly shells,” the durable interior plates of dead gumboot chitons are occasionally found on the beach.

Sometimes dubbed “butterfly shells,” the durable interior plates of dead gumboot chitons are occasionally found on the beach. The shells are bright white and their shape resembles a butterfly.
