Abstract: 1. Commensal Arctonoe vittata marked with a dark band were shown to bite Pisaster ochraceus significantly more than unmarked worms on host Diadora aspera. 2. Arctonoe were shown to search in response to the physical movement of the mantle response. 3. Arctonoe were found to bite, once aroused, if they were situated in a groove and contacted a tube foot. 4. Worms with palps removed were found to miss the tube foot when attempting to bite.
