Snails have thousands of teeth which are used for scraping or cutting food. The teeth are arranged in rows on a chitinous ribbon and together form the radula. A typical radula may have 120 rows of 100 teeth i.e. around 12 000 teeth, though some species may have more than 20 000 teeth. The arrangement and shape of teeth varies from family to family.

Land snails are important environmental indicators and biodiversity predictors and have a role to play in the monitoring of climate change. Their conservation should be a HIGH priority.
Invertebrates make up about 99% of terrestrial biodiversity on our planet. Molluscs are the third most common group after Insects and Fungi. Snails and slugs represent 6% of the world’s terrestrial fauna.

STEVE IRWIN’S TREESNAIL
Found only in the 3 places in the wet tropics of North Queensland, the Snail Whisperer says that like its namesake, Crikey steveirwini is a unique creature with some interesting qualities that set it apart from other land snails.
This is an extremely rare species of snail. So far it has only been found in three locations, all on the summits of high mountains in far north Queensland and at altitudes above 1 000 metres which is quite unusual for Australian land snails.
