Snails and slugs are gastropod, meaning 'stomach foot'. Some gastropods live in ponds, river and even under the sea.
With most slugs and snails, there are no males or females. When two of a kind meet and decide to reproduce, they inject each other with little darts. The darts contain sperm, which find their own way to the unfertilised eggs in each slug or snail.
Sea slugs have gills for breathing underwater, and specialise in eating poisonous animals such as jellyfish. They use the poisons to make themselves nasty to eat, and look every bit dangerous as they are, with bright yellow, pink and red colouring.
