A Guide to the Snails and Slugs of Indiana

This is a guide to the land snails and slugs of Indiana. It is designed to serve as an educational resource for the casual or serious observer (from iNaturalist, for example) to know the nature of snails and identify the species or genus of the most likely encountered shells.​

For completeness, a broader list of snails and their identification and description is also presented - but based only on the information at hand. For a true consideration of Indiana snails, hundreds of more collections and thousands more snails would need to be collected and processed and museum collections would need to be evaluated - a set of tasks beyond the scope of this effort.

​These are the major features of this Guide:

​​​1. About Land Snails - a brief introduction to the biology of land snails.

​2. A Quick Land Snail Guide - a brief description of a few land snails that you might most commonly encounter on a hike or walk in a state park, forest, or other woodland area with the information needed to identify them if not to species, at last to type. It does not include slugs.

​3. A deeper look at Land Snails and Slugs, including:

4 . About Aquatic Snails - a brief intro, comments on structure, and a key to major groups with a species list.

​​​5. Resources - includes "how to photograph snails for identification" and resources for land snails and slugs, as well as aquatic snails.

6. ​If you have any questions, use the Contacts page.
