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 authored a checklist and guide to land snails of Kansas (https://kansasmollusks.wordpress.com/kansas-land-snails/) in my previous (working) life. A list of my snail work is found at the end of the References. I can be emailed at email@example.com.
I developed this simple guide to common snails and this web site to serve as an educational resource for the casual or serious observer (from iNaturalist, for example, where I post as "portageejoe") to know the nature of snails and identify the most likely encountered shells.
