Description and habitat

Medium-sized cigar-shaped chiton up to 50mm in length, dull brown or grey-green, in its northern range frequently mottled in colours ranging from blue to orange. Small grainy riblets cover the outer parts of the valves, the centers being smooth or eroded, a white streak often seen lengthways across the top. The girdle is narrow and may be irregularly banded in dark or light shades. Occurs in sheltered harbours or exposed coasts, from the high intertidal zone to 25m deep, often aggregating in large numbers around the edge of cobbles at the sediment line or just below it.^[1]
