When two hermaphroditic (possessing both male and female reproductive organs) slugs decide to mate, they climb to some elevated place, for example in a bush. After following each other around in a circle for as long as two and a half hours, the two animals entwine and drop from the perch, hanging suspended by a tough mucus strand that may be as long as 25cm (10in). While entwined, each snail everts its penis to its full length of another 10cm (4in), and the mutual exchange of spermatozoa occurs while these penises are wrapped around each other. Both slugs will later lay a clutch of transparent eggs on moist ground under stones or other objects.
