I have not seen a terrestrial (land) snail since I was a kid. We used to call them wood snails. I picked up a board off the ground at my daughter’s home in Arkansas and discovered a Yellow Globelet Snail (Mesodon clausus) on the underside of the wood. The snail was crawling on the board. I placed the snail on a leaf so he/she (most land snails are hemaphrodites) could be seen more easily in the photo. Many snail species are endangered with lots of possible causes which need more study: loss of habitat, pesticides, herbicides, other invasive species, and even salt that we put on the roads during snow/ice storms. I turned this snail over on his back and watched as he/she quickly flipped themselves over.
