Chitons are marine molluscs of varying size.
Chitons have a shell composed of eight separate shell plates or valves, overlap ping slightly at the front and back edges, articulating well with one another; the shell plates are encircled by a skirt known as a girdle.
Chitons can curl up into a ball when dislodged from rocks.
