Hi there, I encountered this glossy snail under a bush in old wet leaves today. Anyone any idea what species this could be? I'd estimate, some kind of Aegopinella, but I'm nit sure which...  Remark: This is a predator snail, who might well have eaten the tiny hair snail I photographed last week, though I sincerely hope not...! Kind regards Attachments:

Are they really predator snails??? Ive seen a video on YouTube with someone with one of these as a pet and they call it a discus snail

Hi,
Amazing photos!
Perhaps it's an Oxychilus... And it's detritivore and coprophagus!

Hi there, thank you for those remarks! I should clarify where I am: I am in Luebeck in Northern Germany. So it cannot be Ventridens ligera, as that species is not native to Germany. Also I just checked (I do not know that species): Ventridens ligera has many more whorls more densely coiled and a conical shell form. Oxychilus could be possible, only the snail was rather small, and it is even better visible in this picture, why I did not think Oxychilus, but Aegopinella. The last whorl, to me, appears quite enlarged, and the snail appears not to have enough whorls for an Oxychilus. But this IS difficult - I don't know glossy snails so well... Kind regards Robert PS: I am quite glad there is so much response here, that's rather uncommon - thank you!! Attachments:

Hi,
Aegopinella and Oxychilus, when become adult, have usually 5 whorls... The snail in your photos has 4 whorls, so maybe it isn't adult! The identification is really hard... Only DNA can give us reliable answers!

Hi there, Perhaps it's an Oxychilus... And it's detritivore and coprophagus! Thanks again for the comments. In the meantime I found pictures of Oxychilus cellarius on biolib.cz, which closely resemble "my" snail. I had found out earlier, that Oxychilus cellarius not only lives in cellars, like the name suggests, but also in caves (got a very good picture from an English cave), but in my area as well in alluvial forests and in gardens among garden waste. Kind regards Robert |

Hi,
So? Maybe it's an Oxychilus cellarius?

Hi simosnail,
yes we both know the same forum, though I am not there very often anymore, because nobody answered by postings...
Anyway: I did not think of Oxychilus draparnaudi, because the snail's shell was hardly 10 mm wide. Of course it could have been a juvenile, which is quite hard to say in a glossy snail.
So I will stay with Oxychilus cellarius, which, as apocalypse rightly points out, is hard to contradict from a photo.
Thanks a lot,
Kind regards
Robert

Hi,
I'm Italian and I came from MG
I think you can search datas about Oxychilus in your country, and after you can compare names and images on the web/books and check what species is the snail in your photos!

Hi, apocalypse, I know you're from MG. That's what I am doing: Comparing books, websites from different countries and my own knowledge. But you can not always say for sure from a photo. Kind regards Robert |
