Project Description

The giant Pacific chiton (Cryptochiton stelleri) is the largest chiton in the world.  Its eight shell plates, which are usually exposed on other chitons, are completely covered with tissue.  This chiton can grow to fourteen inches (35.5 cm) long, and may live for up to forty years.  In the past, the giant Pacific chiton has been used as a food source by the First Nations people of the Pacific Northwest.  Its colouration varies from brown to deep red, with a range that includes Japan, and northern Alaska to southern California.
