}}Chiton olivaceus, the green chiton, is a species of chiton, a marine polyplacophoran mollusk in the family Chitonidae, the typical chitons.[1][2] DescriptionChiton olivaceus can reach a length of {{convert|32|-|40|mm}} and a width of about {{convert|16|mm}}. These large chitons have carinate plates with strongs ribs. The shell is oblong and oval. In the front and rear plates ribs have a radial pattern. The intermediate valves show a sharp beak and rounded sutural plates. Colors are very variable, ranging from olive-gray (hence the common name) to yellow-brown, sometimes black, orange, red or yellow. The girdle surrounding all of the valves is quite large and covered by bristles and scales.[3][4][5]The teeth of these grazers of algae [6] are composed of magnetite, the hardest material usable by a living being. DistributionThis species is common in the Mediterranean sea ( Italy and Greece), but can also to be found in the nearby Atlantic Ocean.[7] HabitatChiton olivaceus occur on a solid substrate, particularly stones and rocks, in the zones of sweeping of the waves, at a low depth.[3]References1. ^URMO: UNESCO-IOC Register of Marine Organisms.
