Some species of chitons are often found in Indian and West Indian foods, and they are used as bait.
There are over 600 species of chitons, and one of the most diverse groups is found on the Pacific Coast. To keep its surface clean of other organisms, a chiton secretes a mucus that swells on contact with water. This touh mantle completely covers the chiton's eight transverse shell plates, and prevents foreign organisms from attaching to the spines of the girdle.
