Received lots of subadult fulica this morning, including at least one umbilicata. As far as I know its just a shell mutation, and probably not a subspecies? But still interesting. I'll check some of the smaller fulica once theyve settled to check for more umbilicata, as Im thinking of breeding them to see if the babies also has the unusual shell shape. I found this picture of an umbilicata shell, the columella shape is much different to normal fulica, and the shell more rounded. www.femorale.com.br/shellphotos/detail.asp?species=Achatina+fulica+umbilicata+Nevill%2C+1879Does anyone on here keep any fulica with this shell shape? |

They sound interesting , will try and get a decent pic of my large fulica , his shell is a wierd shape ,sort of fat round the middle , unless its because he is so big, ive never seen a fulica like him before

Is his columella shaped like in the picture as well? umbilicata has a non-truncated columella, more like Limicolaria than Achatina species.

His shellshape is very unusual, if he has a non-truncated columella like in the link he would be umbilicata. Ive asked an expert on Snails whether umbilicata are a valid subspecies, or just a mutation, Im going to try to produce more though eitherway.

It's really beautiful and interesting Kab, my congratulations!
I would recommend you, to let him to reproduce (even if with a "normal" specimen), then crossing again the offspring, surely that strange trait would be inherited!
At PetSnails we are debating about a new "Gastropods Society" or so, and one of the aims would be the identifying, studying and perhaps breeding and selecting of new variety, that could be not only of "aesthetic" or recreational value, but even deserve attention from genetists
Best Wishes with your wonderful fulica, and please let us know about him!

One of my albino fulica has a shell shape very similar to the photo in your link Kevin, I will get a picture and post it later. Not sure about the columella, will photograph that for you as well.

One of the original, farmed albino fulica I sold had a non-truncated columella, at the time I sold all the farmed ones. Is yours captive bred? would be interesting if its related to that one I sold.

Ive asked an expert on Snails whether umbilicata are a valid subspecies, or just a mutation, Im going to try to produce more though eitherway. I don't think this is a subspecies but a form of fulica.In the "Compendium of landshells" it's listed as Achatina fulica f. umbilicata. I have one of these as well and get a photo of it later. |
