Abstract: 1. Adult Arctonoe vittata were tested in head-on aggressive encounters in the pallial groove of a Cryptochiton host. 2. Arctonoe was found to have intraspecific differences with respect to levels of aggression. 3. The most aggressive worm in a group successfully defends a host against others, evicting conspecifics. 4. Removal of the palps had no effect of the worms' aggression, but antennae removal significantly reduces aggressve behavior.
