Thank you Godzira. All that reading made me wonder, ...could the color of T's be due to only the coarse and fine hairs all over their exo? When you think about it, when they kick off hair off their ab, it's bald and pink. Are the colors only from hair? Anyway, I don't want to start a long thread about it, I read those two, thanks!

www.chilearacnidos.com used to have a picture of a *supposed* "albino rosea".

it basically just looked like a super light rosea, it still had a reddish tint overall.

here's another link to another forum in which i started a thread on the "albino rosea":
http://www.tarantulas.us/forums/showthread.php?t=5858

if you go to that forum and click on the link that takes you to the pic, you will see that chilearacnidos no longer has the pic posted.

ps: as you will notice on the other forum, i state that i do not "doubt this person's taxonomy for a second!". Well times have changed. These days, i question everything that doesn't have solid data or proof. Or in this case, readily available taxonomic data.

I agree that spiders don't have pigmented skin like most albino creatures we may think of, but since spiders come in all sorts of different colors there is definitely some pigment involved somewhere. We're all aware of rare color morphs in any given species. Is it not possible for there to be a super rare morph that involves no pigment where it is usually present? I've never heard of it myself but I don't know if I believe it to be impossible.

I know crickets are not arachnids but you see at least one albino in every dozen or so.

At the BC Arachnoparty this summer, Rick West showed us a photo of an albino T (I think it was a Brachy, I forget). I had always been told that tarantulas could not come out albino, but if Rick West says they can, I believe him. :worship:

A red-eyed tarantula? EEEEK! That'd just be enough to annihilate any hope of them being appreciated by society. Why don't we just give them big pointy fangs?? Oh, wait... nevermind.

Even if there was an albino tarantula, its eyes wouldn't be red. The red eyes in albinos is caused by lack of pigment (duh) and so the blood shows through. Since tarantulas don't have red blood, they wouldn't have red eyes.

Could we give them frankenstein bolts & stitches? Pretty please?

No you don't. They are freshly molted, not albino. Inverts are not capable of producing albino. I do suppose hypothetically there could be a very very rare mutation That would cause a lack in the production of whatever is responsible in their exoskeleton and hair that reflects light. But it is very unlikely if not impossible. And its still not albino. Also the term albino only refers to mammals. All others, even though the term is used often, are not albino, it is improper terminology. I have forgotten the little bit of science I used to know about the specifics of how this works but I'm sure if you look hard enough you can find the science behind it. It's no mystery. Someone knows exactly why.

yes indeed, those are freshly molted crix.


when you say "whatever is responsible in their exoskeleton", i believe you are referring to sclerotin :) or maybe perhaps the chitin..

inverts aren't capable of producing albino? how do you explain what is usually referred to as the albino Narceus americanus millipede? http://www.bugsincyberspace.com/browse1.htm (top left pic on that link) i know milli's are nothing like T's, but they are still inverts :)

i agree that albinism tends to occur mainly in mammals. but i think until we have a true expert come on this thread and post, or until someone finds some authentic & trustworthy research reports on the net, we won't know.

I'm trying to be as objective as possible. i'm just throwing up a few points.

I tend to drop this into most albino T discussion threads I see since back when I joined arachnoboards they all carried this horrible rumor that spiders lacked any pigments.

For an old thread on the pigments present in spiders, see here:

http://www.arachnoboards.com/ab/showthread.php?t=82385

P.S. The link really isn't about albinism, so if that's what you are really interested in...you might just want to skip it.

I believe the older definition of albino is a mammal lacking melanin so any animal that doesn't have melanin as a pigment or isn't a mammal can't by definition be albino. Its just such a common misusage of terminology that it is now widely accepted. Older definitions have it listed for just mammals and newer definitions have started to say something like animals lacking dark pigment; especially mammals//// to compensate for the actual accepted usage of the word (I believe this to be the case, I'm no english major). At any rate its splitting hairs. Its great to see that there can be inverts that have lighter colors wether that is technically albino or not. I just hope some of them will survive to adulthood so we can see if we are able to isolate that trait or if its just a freak mutation that can't be passed on. Lets keep our fingers crossed!!!!!
