Chiton tuberculatus Linnaeus, 1758

This three inch chiton is one of the handsome scaled-girdle chitons of the Caribbean. The valve color is a dull grayish green or greenish brown. Some valves have a dark-brown arrow-shaped patch on the dorsal ridge. The lateral areas have five irregular, radiating cords. Central areas are smooth at the top and eight to nine strong, wavy, longitudinal ribs on the sides. The girdle color is alternating zones of whitish, green or black. The scales appear to be slightly higher than broad.
