Once ejected through the slit and onto the immobilized creature, a female parasite will position its tapered front at the anal ring. This is when it uses the tongue tendrils to force the anus open and wriggle inside to merge with the host. Male parasites will sense whether or not the host is already infected: if they are, he will be ejected just like the female, so that he can have sex with the female inside the host and fertilize any eggs that might be ready to be laid. However, if his target is not host to a female he'll often punish his foe using his larger body as leverage. By the time that this process has finished, the larger body has usually dried up enough for the creature being held to break free of its now brittle confines.
