Courting or fighting?

[shaydeesnail]

Maybe a silly question, but just to make sure!
I assumed my Cepaea were getting their freak on, but they are biting each other a lot, so that the other flinches back into the shell for a second then comes out and bites the other back!
Snails don't fight do they?
Just making sure this is normal haha!

I'd guess it is courting. The only fighting I've seen always results with the attacked animal retreating, thus ending the "fight" in one bite. This with my slugs, Deroceras invadens, which has the most violent courting I've heard of. When courting they bite back, otherwise it's a warning bite which results in the other running always, unless obstructed somehow. With other species that do not hunt their own kind for dinner, never heard of proper fights outside mating.
