Interesting. I've only seen eyes at the base of the tentacles in aquatic snails before.
I've tried googling info on this for 20 minutes now, but I can't find anything related. Need to try a few more search terms...

Lol, as a warning to others, do not combine search terms "tentacle" and "asia". I wasn't thinking of the obvious consequences, and did just that.

Wow! Can't say if it is cute or not. Interesting snail! Did it say how large it was?

This is a beautiful and interesting snail ! As pinkunicorn mentions the eyes are just above the base of the tentacle. Coffee is also right to identify it as a Schistiloma, though I can't confirm the actual species. The shell is probably around an inch in length. Schistiloma are a genus of snails from the Malaysian Peninsular within the family Pupinidae ( around 120 different species, mostly from central Asia ). They bear an operculum ( trapdoor ), like many of the marine and aquatic snails. In this image you can see part of the operculum, just to the right of the aperture ontop of the snail ( tilted view ). Here you can see the operculum of a Schistiloma sp. In its closed position : Special thanks to Andy Paul for his excellent photos.

Ooh thanks for putting us out of our misery with the species!
Do you happen to know anything of its lungs? It has so many shared traits with aquatics it makes me wonder if its ancestors were aquatic at some point. It's happened in many animals, why not snails. The eyes are so weird... are there other land snails in other families with eyes like that? I know eyes have evolved in so many ways, even similar eyes many times in unrelated species but still makes me wonder. The tentacles arealso typical for aquatics.

Pinkunicorn asked : Do you happen to know anything of its lungs? ...well, you got me out on a limb here as I'm in the middle of Ghana at the moment (no library), but easiest answer to give you would be that the the family Pupinidae are prosobranch; along with the bulk of the marine and fresh water mollusks, and some other landsnails ( e.g. families Helicinidae, Cyclophoridae, Pomatiasidae and Chondropomatidae ). Prosobranch means gills in front (of the heart). Further reading look here : en.wikipedia.org/wiki/Prosobranchiaen.wikipedia.org/wiki/Taxonomy_of_the_Gastropoda_%28Ponder_%26_Lindberg,_1997%29 The taxonomy of the gastropods is changing rapidly, most recently by Bouchet & Rocroi, 2005.

But clearly the snails over all apearence is nothign alike

Tropidophora cuveriana is a discoid shell of about 2" endemic to Madagascar forests, already mentioned on the forum : petsnails.proboards.com/index.cgi?board=general&action=display&thread=10388. It is also probably prosobranch ( has an operculum ) so could well be some similarities in animal features, but otherwise color and shape of animal and shell are quite different. Maybe Oscar101 can post a pic of the animal for comparison ?

Certainly can will have to get some while their active for a body comparison now that I have a new camera. for now though hears some shell pictures and a pair of recordings. Unfortunatly the recordings were done with my webcam before I got the new camera so I apologise for the bad quality. In this video, notice how the snail has 2 "feet" rather than a "central foot" and how it apears to "walk" rather than slide!!! www.youtube.com/watch?v=el5_l-TmTAs(for best example of "feet" forward to 6:25 and watch from their) In this video, theirs a better example of the snails eyes, though the quality is not great so it would be difficult to notice if you didnt know what you were looking for. this video also shows how the snail traps itself in its shell for protection towards the end of the recording another "feet example at 4:15, trap door example at 5:15 onwards. www.youtube.com/watch?v=J0EbtWcCec8

Would be interesting to compare details with your Tropidophora animal, the footage on UTube is unclear. The operculum in your shell looks hard, calcerous and opaque ?
