These are really quite beautiful slugs (well I guess it's all relative) and an interesting species to boot. They have quite an extraordinary method of mating - entwined together dangling at the end of a string of mucus. I'm pretty sure that Rik has photos of this species mating (Rik?).
I was quite surprised to see (what appears to be) this near cannibalistic behaviour and I did watched it for some time. It's always possible of course that the slug may have found some other source of food in an empty snail shell.
