Description: Color is usually gray-brown and white. Radiating ribs of shell are both light and dark. There is a small opening at the peak (Ref. 312).
It has a shell length of 7 cm long (Ref. 312). Occurs at low intertidal zones. Omnivorous; encrusting bryozoans are sometimes consumed in preference to algae. When under attack by a sea star, it will extend its mantle flap over its foot and shell so that the tube feet of the star fish cannot grasp it (Ref. 312).
