Facts about Snails
- Snails are an invertebrate, which means they do not have a backbone. Instead, snails can change the shape of their body to safely fit inside their shell.
- A snail shell is made of calcium carbonate, similar to a seashell. Snails grow the size of their shell throughout their life.
- There are thousands of different snail species. Some live on land and some snails live in the water.
- Most snails can see, although their vision is not very good. Instead snails use tentacles on their head to take in information about their environment. Land snails have two sets of tentacles and water snails have only one set of tentacles.
- Depending on the species and their habitat, snails can have lungs or gills.
- Snails have a brain.
