"donkey ear" pond snail ID?

[cellodaisy]

I guess it doesn't really matter... they are what they are. I would be curious to know, though, so I can learn more about them. I find pretty much everything fascinating. I know they're common, but common ≠ boring.

Hmm, now I'm not sure about mine. I got one out a few minutes ago and snapped some pics. It still definitely looks different from yours.

That is a pond snail not a bladder the antenna give it away.

If you're referring to mine, the confusion is which particular species of pond snail. Same difficulty as cellodaisy is having. Mine are about 0.75"(2cm), so they're fairly good sized snails.

I think the dextral shell gave it away long before the antenna did.

...paper, is that one taken from the wild, or did it come in as a hitchhiker?

The shell too but I always look at the antenna first.....

Hitchhiker. A few months ago I dumped excess hornwort from my 75g into my dad's watergarden. All I can figure is the snails were outcompeted for food in the 75 by the ramshorns and mts (they decimated my bladder snail population), and that's why I don't have any in there.

Sorry to hijack your thread cellodaisy.

Give it up for minute details!

Could be Stagnicola elodes. I don't think it's all that common in the aquarium hobby, but it is ocassionaly marketed as a snail for ponds. It can also be found in the wild in the US.. which pretty much makes my previous question of where you got them rather pointless.

Sorry to hijack your thread cellodaisy.

Hijacking threads makes the world go 'round.
...cello's question was *sorta* answer, so she can't be *too* mad.

Hmm, I looked the stagnicolas up, looks fairly similar. I just can't really tell for sure, mine look a little larger in the last whirl. I did find several reference pages online:

Very nice pictorial guide to snail IDs

Nice little lymnaea chart

this one has comparative pics halfway down.

Haha... hijack away! We're still talking about Lymnaea identification, so I'm a happy camper.
