Over the weekend I found these guys while on patrol ;D (there was actually a ton more but I only picked a few up) I'm pretty sure they are cepaea nemoralis but I was hoping for some input just in case I'm wrong  The first two I believe are adults, the others are about half the size or smaller than them and I believe they still have quite a bit of growing to do ^_^ (6 snails in all) Sorry not all pics are the best quality but there should be enough really good, clear ones for identification purposes =] Spam pics inc! |

The first one is Cepea nemoralis but I'm not sure about the rest as I can't see the usual brown stripe at the lip of the shell, it looks like a white stripe in which case it would be Cepea hortensis (which would fit in with the fact they're smaller) but it might be new growth so I can't be sure. Sorry :/

The first and second are actually the same size. The other ones are smaller but I believe they are too small even to be a fully grown hortensis. I could be wrong, i'll have to double check how big they get. However the other ones did not seem to have a definitive lip imo. I suppose time will tell =] There were so many snails crawling around in the area I found them. They ranged in size from Darth Vader(and slightly larger!) to even smaller than the smallest one I picked up. Is the only way to tell Hortensis and Nemoralis apart the color of the lip of the shell? (Which apparently can't be too reliable either as both variants have been known to have both the white and darker brown lips, very confusing  ) Like is there any other differences in the structure of the shell at all? Would the Hortensis and Nemoralis be found living together in one area? |

Hi, you've chosen some lovely snails. Where some of your snails lack the black lip it may indicate hortensis, but the black lip doesn't always show well in young cepaea nemoralis, as you've found out. In adult snails the shells of hortensis is generally slightly larger. Also lighter skin is a cammon feature in hortensis, it's usually light cream, but again this doesn't form a positive i.d. I can't find any shell pictures in the links you provided. If you don't mind me doing so here's a link to the main page of the helicidae group www.conchology.be/?t=65&family=HELICIDAECartman looks like a hortensis Sorry - not much help there, but lovely snails  |

Hmm.. don't know why those links aren't working, I even double checked them after I posted. Oh well, broken links ftw  I think what I'll do is take pictures of all of the smaller ones next to a ruler and then in a few weeks I'll be able to see if they've grown or not (as if I wouldn't be able to tell anyways XD) but atleast that way I know for sure how big they were/are ;D That should help some in determining if they are indead hortensis or still growing so it can't be determined just yet. And thank you for the compliments! ^_^ ...and oh gawd Coyote, you've created a snail loving monster lol I think I'll be up to 3 tanks once the hatchlings grow! >.< I'm already moving around my entire room and getting new furniture now with the second tank Think I should have froze like half the otala lactea eggs instead of thinking they prob wouldn't hatch at all and then ended up hatching them all >.> |

Hi, I find it a bit difficult to say something clear so early. Apart from the first one, I'd say that all snails are juveniles. So either we should wait until they are fully grown, in which case we'd also see the apertural lip and its colour, or we check for their love darts, which would be a definitive character. But that, too, we could only see, when the snails are mature... Judging from the band patterns I should say, all snails are nemoralis, but I shall not be sued Kind regards Robert |
