What is Axanthic ?

I belive its juz a name and the actual term for yellow pigmentation would be Euxanthic.

Here's wad I found from the dictionary

Euxanthic:

\Eux*an"thic\a. (Chem.) Having a yellow color; pertaining to, derived from, or resembling, euxanthin.

Euxanthic acid (Chem.), a yellow, crystalline, organic acid, extracted from euxanthin.

I did a search on axanthic and somehow that didnt turn up in the dictionary.. hmm

I disagree. Albinism has various forms. It need not be a total lack of colour pigmentation. There are differences between oculocutaneous albinism and ocular albinism just to give two examples.

Its quite normal if they have black eyes too. Or for that matter blue eyes or even brown eyes.

what they're saying is axanthic is the lack of yellow pigmentation while Euxanthic is the term for yellow pigmentation. Seems like one has while the other has not. But I've really no idea of axanthic being an English word at all.

the yellowish coloration could be due to the age. When young aros look transuculent so the yellowishness could be due to the color of the flesh under the scales which are clear?

or simply that the breed genetics isn't perfected yet.

I thought this is supposed to be a defect ? or do u mean Panda is actually trying to breed this to perfection ?

It doesnt seem to turn up in the dictionary, however doing a search on the web , I had results of axanthic pythons and Axolotls and the explanation given are as follows , not sure if it applies to aro but here it goes :

"The second kind of albino I will mention is the axanthic albino. It has normal pigment cell migration but is homozygous for the albino gene and the axanthic gene (a/a and ax/ax), meaning it lacks melanophores, xanthophores and iridophores. It is almost white, but becomes yellow with age due to the accumulation of riboflavins from its diet. "

As for albinos
"Phenotype is albino a/a (lacking melanophores). There are many kinds of phenotypically-different albino axolotl. Here are some of them. The first is the golden albino (D/D a/a or D/d a/a). It has normal migration of pigment cells, but lacks melanophores, hence the yellow/gold appearance."

So Axanthic is a form of albinoism ?

Really dunno anything abt this term " Axanthic " but the pics shown seems to be those of albinism. Albinism has various degrees. A lot of albino people have poor eyesight but some can see very well. I have an albino classmate, coincidentally named Fong too. He's perfectly normal .

I think u all can enlighten me better

I have never come across this word leucistic

English word ?

i'd think the panda ones should be Xanthic, instead of Axanthic... which means they have an abnormally high amount of yellow pigments, instead of the lack of it.

Whether these words are english or not, I have no idea though.

plausible .... i know wat's xanthic .... but seriously those aros shown seems to exhibit a certain level of albinism rather than having a single dominant yellow pigment .... the eyes are a sure give away to a genetic defect


by the way, I've been wanting to ask ... are u Dan10's brother ?
