It gets even weirder yet!!!
This just in from wikipedia;
"Apophallation is a commonly seen practice among many slugs. In apophallating species, the penis curls like a corkscrew and during mating often becomes entangled in the mate's genitalia. Apophallation allows the slugs to separate themselves by one or both of the slugs chewing off the other's penis. Once its penis has been removed, the slug is still able to mate using only the female parts of its reproductive system."
EEEEEGAD!!!!!!!!!
Hi LaFemme,
Actually, these ones aren't so big really. The ones on the outer south coast of BC, like on Vancouver Island get so big they call them banana slugs...and yes, they are that big.
