Description
Cryptoconchus porosus can reach a length of about 45–75 millimetres (1.8–3.0 in).[4][5] The valves are almost completely covered by a fleshy nodular girdle. They have many gills, but no eyes. The shell consist of eight interlocking plates surrounded by the girdle, but young specimens usually have only seven plates. Color of the surface ranges from brown to bright orange, while the underside is often blue.[6]
Distribution and habitat
Cryptoconchus porosus are present in New Zealand [2][7] and Madagascar.[8] These quite common grazers prefer outer exposed rocks in areas of sweeping of the waves, in the low intertidal and shallow subtidal zone.[6]
