I hope you are all having a wonderful day! As I said in one of my latest posts, I’m starting a snail rescue! I need help identifying the first few snails for adoption. Let’s begin shall we! Thanks in advance! (All snails found in south of TN)
The first are Zucchini and Squash: Details: they are both similar sizes, but zucchini has a more beat up shell. Which makes me think he’s older. Zucchini’s shell size: 4-3 mm. Squash’s shell size: 2-3 mm. youtu.be/SHolASfcoF0
Next we have Finn! Details: his shell size is 4 mm, and looks the same as the others. No teeth on shell, and light colored body. youtu.be/Gku45xAbO_w
Next is Aussie! Details: he has a dark, almost black, body. He also has teeth on his shell that you will see in the video. Shell size: 6-7 mm.
unfortunately your pictures are not very helpful (out of focus, f.e.). Sorry, sorry............ .
It's too bad, but I know nearly nothing about north American land snails. Nevertheless I think "Aussie" should belong to the family Polygyridae, genus Tridopsis. There are several species of this genus in Tennessee, at least T. hopetonensis and T. tennesseensis (perhaps even T. fallax??). Perhaps you can compare with these species.
There are sure many people living in the US on this forum who are very familiar with the land snails in their neighborhood.
