Slugs, Snails & Bivalves

Slugs, snails and bivalves are molluscs - a group that also includes Octopus, Squid and Cuttlefish, and one of the most successful invertebrate groups to have evolved. Most mollusc species are found in oceans but a few have adapted to live in freshwater and some can live on dry land. These terrestrial species move by secreting mucus to lubricate their path but this results in the loss of water and all are vulnerable to dessication. To avoid this they either live in damp habitats or retreat into their shells during dryer weather.

Around 100 snail and bivalve species and 25 slug species have been recorded in Leicestershire and Rutland (VC55). Others are likely to be found as some species are expanding their range and may appear in our area.
