About Cyanoplax keepiana (S.S.Berry, 1948)
Cyanoplax keepiana, commonly called Keep's chiton, is a chiton species native to the Pacific coast of North America. As noted by the Cabrillo Marine Aquarium in San Pedro, Keep's chiton has brilliant blue markings on its plates that can only be properly seen with a hand lens. These are small chitons, reaching less than an inch (18 millimeters) in length. They typically live in fairly warm water, in sandy or rocky tide pools ranging from Cayucos, California, to Mexico's Revillagigedo Islands. S. Stillman Berry first formally described this species for science in 1948.
