Hello,

Along with the large ammount of  young toads ive found ( I think they have had quite a succesful year around my area), i found one which did look unusual. It has grey-black skin, which is sort of transloucent. Underneith it is pale, and i can almost see the organs inside it. THe most unususl think about it is that its eyes are compley black, there is not the distingtive bronzy eyes like a normal toad. It doesnt appear to have any of the brownd pigment in it skin, so im wondering wether it could be classed as an albino.

I will try and get a picture but it could be weeks or even months

Thanks

AJfr0ggy

sounds interesting, there is a picture on Page 94 of the recently published Amphibians and Reptiles a natural history of the British Herpetofauna (soft back issue) showing an albino common toad, though it's black and white the eye looks like it is pink as would be normal for an albino animal, perhaps yours is melanistic?

I was thinking it may be melatistic, but i think it is completly lacking they pigment which causes brown, which sort of means it would be an albino. Would melanistic have grey transloucent skin?

Hi, albino would strictly mean lacking any pigment at all, the picture I referred to shows a white animal with pink eyes. I'm not sure of the term for lacking brown pigment, maybe someone else knows?

thanks

Im gutted, the little thing has escaped!
I seached its entire 4' glass avquarium, i found all the toads other than that one. After looking at the viv i decided it may be possibe to jump from the water bowl up to a bit of glass which it could have stuck to, but why the black one out of all 7?
at least it can survive as i found 4 wild ones around it
Im not sure when it escpaed as i last saw it yesterday
Out of all the days it had to be the day before the photo
I may have the chance of finding it in my garden, if not i'd have to wait until next year when all the babies have morphed, providing its a good year. THere is also a small chance that it may be hiding deep in the sibstrate but i cleared all the loose soil. 

I did however take some photos of some wild ones in my garden, i think these are from this year, wuite big allready!

Last week I found this strange male, obviously with the same mutation as the last one:

It is now with a female, and i hope it successfully breeds in my nearby lake where i found it.
