The Gastropoda are a large group molluscs with over 60000 species known. They inhabit practically every known habitat: from mountain tops to deserts to the abyssal depths of the deepest oceans. The most familiar species are the land snails and slugs.

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.
The chitons are an exclusively marine group that are highly adapted to life in the intertidal zone.
