I am Joe Arruda, retired Emeritus Professor of Biology from Pittsburg (KS) State University now living in southeast Indiana. I am interested in land snails and prepared a checklist and guide to land snails of Kansas (https://kansasmollusks.wordpress.com/kansas-land-snails/).

I completed a quick review of Indiana land snails based on museum collections and other sources. It includes a quick guide to common land snails such as many iNaturalist observers would run across and state county-level occurrence maps. It also includes some information on aquatic snails. Find it at https://www.indianasnails.com/.

​If you look at snail posts at iNaturalist.com, most only give one view - the top usually. For the most proper identification of "wider than tall" snails, at least three views are needed: top, bottom, and side. Actually, two separate side views are better – one with the aperture, any teeth, and clearly showing the profile of the shell to help determine the type of spire - and one more close directly into the aperture showing the nature of any teeth. For "taller than wide" snails a front view of the entire snail with the aperture and a closer view of the aperture will usually do.

Avoid holding the shell as your fingers can cover things to see - rather, lay the shell in the groove of your touching fingers and position it. Clean out any dirt and debris. If the snail is alive, try to gently tease it back in the shell. Even if yo can keep it in to take a photo, you can add a description in the notes.
