Hi everyone!

I have something amazing with one of my spider.
I have two O. Aureotibialis 6 instars, one of they is look orderly - he is black with yellow. But the second T looks very strange, he had molted 24.02.2006., but looks so, as if had molted yesterday! That is to say he light-gray with nearly white exoskeleton, his fangs very light, quite not brown even. This happens with him not first once. I paid attention to his exterior after previous moltings too, he always was lighter than the first T.
His exoskeleton is hard by touch, fangs hard too, but complete pigmentation is absent.

Had anyone faced with such strange phenomena? Much interesting the specialists opinion on this subject.

You don't happen to have a picture of it? It would be interesting to see it :)

Regrettably, I have no pictures. Simply, this spider looks so, as if has molted right before. So see on this is unnecessary.

Hi Pandora,

Could the other one now have matured into a male? Males are sexually dimorphic from females

Hi, Ray!
No, they're both female! They 1" BL and 2" in LS.

This is a the normal T http://www.pandora.rdh.ru/foto/O.aureotibialis-7L-f5.jpg , he much differs from the second T.

<edit>
P.S.: If I'll have a possibility in this weekend, that I'll take pictures these spiders together with each other for comparison.

from the sounds of it, its like your saying the second one is albino. I havent ever heard of this happening in Inverts, and didnt think it was possible. But then again I dont claim to be an expert to any degree so you never know.

What a good opportunity for a little quote: ;)
Tarantulas and other arachnids said:
At this point *(after moulting)* it will be very pale, even white in younger specimens. The cuticle will darken as it hardens. This is due to the chemical processes going on, termed "tanning". The color of arthropod cuticle is in part due to its structure, rather than pigment, which is why we never see albino insects or spiders

and thus my thinking that it wasnt possible for albino inverts has been proven. Thanks Cirith. Too bad, I love albino snakes, and albino inverts I bet would have some cool coloration

Albino? Ha-ha! But realy must he not be white? :)
So, I'm waiting for more opinions.

Cirith Ungol, this can be a truth about cuticle structure. But cuticle of my spider is hard.

Sorry, but I must leave the city, I'll be back tomorrow for continue our discussion.

As far as I have read it is impossible for spiders to be Albino. They do not have pigmentation the same way as vertabrates.

It's certainly interesting to hear about such things, but i think without pictures it's fairly useless to proclaim an IN(-)CREDIBLE EVENT and just hope for people to imagine it. I hope i provoked you into borrowing some friend's camera to post a picture. It can't be that hard.
Sorry about not so good english and no offence.


Zdravstvuj!

Damn, beat me to it, was planning on quoting the exact same lines.;)

Really want to see some pics of it though, I'm quite curious about it.

Hi, guys! Privet, dzony!
If you never saw the tarantulas after molting, then I'll post the pics tomorrow :D
Joke :D Indeed this looks very interesting, particularly in comparison with normal spider.
I'll feed my incredible spider today, and tomorrow I'll tell how this had passed to not remain the doubts in his orderly condition.

I have ;)

and on this page you can see another lobster that is half albino, half normal coloration and also half female and half male. You have to scroll down a bit though.

I wonder if any other inverts have produced some type of albinoism.

T's do not have pigment in their exoskeletons...
