Hi diego, might be a crazy "scalarid" form of a normally much flatter species (but I don't think it's a Cepaea variant). Might be it's family Bradybaenidae, perhaps genus Helicostyla (well known from the Philippines). Is it really sinistral (left-handed) or is the picture mirrored?? I think we need more and better pictures (a front view showing the aperture = opening, the exact shape of the shell and so on). Kind regards: wolf
snail shells can be "right-handed" (= dextral) or "left-handed" (= sinistral), because there are two different (opposite) directions of coiling. How to tell? It's very easy: take a shell with the tip (= apex) at the top and the opening (= aperture) at the bottom. The aperture points directly to you (compare with the following picture).
If a shell (held in this way) has its opening on the right side, then the shell is "right-handed" (= dextral), if the opening is at the left side, then its "left-handed" (= sinistral). In this picture the specimen on the left side is dextral and the specimen on the right side is sinistral. In your picture we're talking about ("extra large cepaea") the specimen is left-handed, obviously (or the picture is mirrored!).
Hi diego, I can only see the pictures in your first post (Jan 19th). Did you try to post some other pictures? Where is the specimen from? How large is the shell (shell hight)? Did you find some Helicostyla species where you live? Btw: the sentence on your T-shirt (avatar) is mirrored. Was it printed in this way? Kind regards: wolf
thanks a lot for embedding the links for your pictures.
Now we have some uncertainties: the specimen on your last pictures is dextral. The specimen on your first pictures was sinistral. So which pictures are correct? I still suppose the first pictures to be mirrored. Where was the specimen found? What is the shell hight? Is it sinistral or dextral? Did you find similar specimens? We can't find an answer without further information. I still think it might be a Helicostyla species (at least family Bradybaenidae). There are lots of species in the Helicostyla genus, most of them highly variable in dyeing pattern.

it is sinistral so the pictures where it looks dextral is mirrored i found it in my grandfathers farm where it meets the jungle the shell height is 2 cm and shell length is 3 cm it is also fully grown because it has a thickened lip at the edge of his shell btw i named him samson
