This is a small nudibranch that reaches a maximum length of only about 1 inch.   Onchidoris bilamellata is cream colored with brown or red-brown blotches and has a knobby texture.   While juveniles of this species feed on encrusting bryozoans, adults prey on acorn barnacles.   It can be found on rocks and pilings from the low intertidal to water 60 feet deep.     Another common name for it is the rough mantled doris.
