Slugs and snails belong to a group of
creatures called molluscs. All molluscs have
soft bodies. Some of them, like snails, carry a
shell where they can hide. Other molluscs, like
squid and octopuses, do not have shells.
Slugs and snails are also called gastropods. They are given this
strange name, which means ‘stomach foot’, because under their
stomach they have just one foot. They use this foot to glide around.
Slime is squeezed out of their foot. This makes it easier for them to
move. They just glide along on their slime as they move across the
ground. They also use it when they climb on fences and plants.
Gastropods are not very popular with farmers and gardeners because
they feed mostly on plants. They may not be very big but they can eat
a lot and they have lots of friends to help them. Gastropods’ tongues
are a bit like cheese graters, scraping food off the plants in the small
pieces they like to eat.

Slugs and snails like warm and damp environments. If it gets too
dry for them, they can use dried slime to stick themselves to a hard
surface. They just stay there until it becomes damp again and then
they move on.

Even if you do not see any slugs or snails in your garden, you can tell if
they have visited. They leave trails of dried slime on paths and fences
and trails of destruction through your flowerbeds.
