    The polyplacophora have no eyes. However all known species of chitons possess unusual organs scattered across, and embedded in, their tegmentum. These are typically minute (too small to be seen with the unaided eye), are crystalline and are referred to as aesthetes.
    Polyplacophorans include about 600 extant species. Entirely marine, they inhabit hard bottoms and rocky coasts in all of the world's oceans. Although commonly intertidal, living chitons have been dredged from waters as deep as 7000 m. Of the two subclasses, Paleoloricata and Neoloricata, only the latter is represented by living examples.
    The Polyplacophora, commonly called chitons, are strictly benthic mollusks, exclusively marine, characterized by a flattened body with bilateral symmetry, presently covered by a shell formed by eight superimposed dorsal plates, imbricate and articulated.
    The class Polyplacophora extends back to the Late Cambrian Period with the early genus Matthevia. Some fossil species had only seven plates. Examples of the order Paleoloricata are found from the Late Cambrian through the Late Cretaceous. The order Neoloricata extends from the present back to the Mississippian Period.
