Parasitism:

If the larger body controlled by the smaller organism manages to defeat or incapacitate an enemy that would be receptive to parasitization, the organism moves in to hold onto the future host with hidden pincer-ended limbs located behind the jaws. This helps to expose the soon-to-be-occupied anal cavity. Once the desired hole is found, the sand worm excretes an especially slippery version of its secretions on the host’s cavity. A couple of its long prehensile tongues are then used to massage the liquid further into the hole. After this is done, the tongues retract and the worm locks its body into position, essentially trapping the victim. The majority of the head where the smaller parasite first entered splits open, exposing the neural slit where the parasite is located, and the ejection process begins.
