Pharyngula will be much linked for the video, and much quoted for this awe-inspiring description of gastropod love:

Oh, my. This video from the BBC of slugs mating is spectacular—it’s got mucus ropes, everting male organs, entwining penises, and penises forming a translucent flower-like globe. It made me feel rather homely and inadequate, truth to tell, but wow…appreciative at the same time.

He’s right. It’s a lot like what a friend of mine always used to say about lesbian sex: “really sort of poetic, and interesting to watch.”
