Claim: Callochiton crocinus is a species of chiton, marine molluscs with protective shells composed of eight separate valves that overap.
Evidence: Callochiton crocinus is a species of chiton or "sea cradle" in the family Callochitonidae. Chitons /ˈkaɪtənz/ are marine molluscs of varying size in the class Polyplacophora /ˌpɒlipləˈkɒfərə/, formerly known as Amphineura. Chitons have a shell composed of eight separate shell plates or valves. These plates overlap slightly at the front and back edges, and yet articulate well with one another.
