ID'ing some snails?

[auxout]

Hi, I am trying to ID some snails I found. I was cleaning up some of my property and discovered a (colony?) of snails, a few hundred at the least. It is rather humorous I was searching for a store to buy some snails from last month and no one sells them. :duh:

I tried searching but so far I haven't been able to find a good site with pictures to help me ID them. I am trying to see if they are actually a native species, because then I will leave them alone. My state DNR site was not much help, they have a list of species but no pictures, still searching.

I took some pics and put them here

sorry for the blurriness cell phone cam, also there are these white blob things with the snails they look kind of like tiny larvae, you can sort of see them in the pics.

Thanks for any info!

Oooohhh....Fascinating creatures and you would think I am silly for rescuing a lone Lymnaea stagnalis that could have been harassed by the goldfish! Any more pics of it especially ones where it is showing off its actual appearance, not just the shell?

I will try to get more pictures, its kind of hard with a cell phone to get close while standing in the mud. I'll see what I can come up with.

I am kind of shocked because I worked with waterways/wetlands/ditches for some 2 1/2 years and never saw a concentration like this, I can't recall finding any in all my travels inspecting projects. So I kind of want to preserve this little area they have.

EDIT: Ok so I went back out there and I got pictures of one that was out of his shell upside down sucking the surface, the problem is my cell phone has no macro mode so they still look like crap. I am going to try to get ahold of a better camera tommorow. But I went out to the furthest pool to see what was going on out there and as you can see tons of little black dots. Tadpoles!

I got my suspicion right. It's a Lymnaea stagnalis. See this link!

Waiting for better pics. Hard to tell right now :)

How could you possibly tell it's stagnalis, given it's small size? Could be a number of various Lymnaeidae species.

Aren't these those donkey eared snails?

I didn't forget about this, just slightly impossible to get pictures right now since its been raining for 2 days, snails have at least a foot of water over them now :D
