Sis forSnail

Snails can be found on land and in the water, both freshwater and the sea. A snail without a shell is called a slug. Snails range in size from smaller than your little fingernail to a sea snail that can grow to 30 inches long. The biggest land snail is only grows to 12 inches long. They come in a wide variety of colours and patterns. Snails have a pair of eyes on stalks and a pair of feelers below them, to stop it bumping into things. It can suck both its feelers and eyes into its body for safety, and it can hide in its shell if it is disturbed. Snails have one foot that they "walk" with. They eat by scraping the top layer of their food with their tongue, which is covered in tiny sharp teeth. If you listen hard to a snail when it is eating, you can hear it scraping.
