mating snails - North Island, New Zealand - November 2005

Gastropods are hermaphroditic, with each individual possessing both male and female sex organs. The courtship behaviour of snails and slugs is amazingly complex in some species, involving long 'chases' and/or mutual caressing with their tentacles and lips. Copulation often requires several attempts since both sets of genetalia must interact simultaneously.
