They look like lovely standard fulicas to me. If they were going to be albino shelled, they'd be so from birth, surely.
They're very light, but not albino. Beautiful snails though ;D

On page 2 I've posted the pic of mine and Arno's from when they first arrived, and a pic of what mine looked like at the time of posting. They were obviously yellow when they first arrived, none of my normal fulica babies have been like that. And none have had bodies that light. (Yes I know fulica vary a lot but I've seen a lot of fulica babies lol) I will charge the camera battery up and try and get some pics of mine, they still look yellow (to me at least). The camera normally washes the yellow out though, but I'll try the different settings. Did a google search quickly though, and if you look at this pic it has bands of browny red on it's shell. achatina.unnat.ru/Photo/R0010768.jpg

Hmmm interesting, I'm assuming it's just snails that have bred out the colouring rather than albinoism, although I'm not sure on snaily genetics, if they were true albinos their body would be white too? Clutching at straws here and dont really know what I'm talking about so shall leave it to the snail-experts *lol* Sarah's last piccies do look like normal fulicas, but her previous pics showed they were lighter. I think this is one for Paul

As far as I know they are only classed as albino shelled not albino. Not sure though. The google search didn't show me any with albino bodies, but I would assume it's possible?
Gabi, does it work the same way as with snails getting an albino body then?
I just thought they were like iredalei, they just go yellow whether they have an albino gene or not. Or can you get iredalei with normal shells?! Argh so confusing.
Doesn't help that I know *$^£ all about genetics rofl.

It seems the albino thing is related to 2 things. Shell and body and they are separate. You can basically get albino-shelled, normal-bodies; albino-shelled, albino-bodied; normal-shelled, normal-bodied.
Most determinations were made primarily from shells so rodatzi are really fulica with albino shells, with no mention of the body. However, whether rodatzi are truly albino or just a plain-shelled variety is questionable. They could have simply evolved progressively plainer shells but it is possible they are albinos of some form. The question remains because if rodatzi are albino and a normal fulica gives birth to an plain-shelled baby, is that considered albino or rodatzi?
Bequaert says "It is little more than the albino race of subspecies. hamillei" but no genetic studies were done.
I'd like to see how an albino-shelled baby from a normal fulica measures up to a rodatzi.

I assume (and forgive me if I'm way off) that because rodatzis are a variation of "normal" fulicas, it's more like variations in say dog, cat, rat etc colours, not a distinct separate species? They look normal fulica to me.
Am I right in thinking that mutations in shell colours aren't "true" genetic albinism at all and just labelled that out of a lack of another term? Because I can't get my head around this half and half idea - a genetic makeup for albinism would surely mean the whole snail lacking any pigment. Is it possible that some other factor is at play which limits the extent of lack of pigment to specific areas? Again, not true albinism, just lack of pigment in parts, much like vitiligo (except with set patterns).
I do know that there are certain animals that can be half way to albino - my new fish for example. He is a chocolate albino coloured plec, which means he wasn't born pink like other albinos, but was born a copper colour with red eyes rather than pink. However, his colour is uniform to the whole of him, not half albino and half normal.

You may be right, but that's assuming the gene responsible for shell pigment is also responsible for body colour. The albino margies and reticulata we've seen are definitely albinos, they're bodies are completely without pigment, and yet both have normal shells. So I think there must be some separation between shell and body pigments. But I agree, I suppose an albino in the truest sense of the word would be a snail without pigment in shell and body.

well i will keep updating and all we can do is wait and see if the shell gets lighter or stays normal :-)
