Very strange Axolotl color morph...
This is a discussion on Very strange Axolotl color morph... within the Axolotl General Discussion forums, part of the Axolotls (Ambystoma mexicanum) category; I am holding on to it for breeding in the future. Hopefully there will be more!...

Sinead's right, the male was white albino and the female was a wild-type. This is the only larvae from the clutch (originally 200 larvae)that was different from the rest. None of it's sibblings are white or gold albino, all are wild-type and leucistic. Some of the leucistics have lighter eyes than I am used to, or I'm just seeing things, I'll try to post a pic of some of them.

He's grown quite a bit. Now he's about 3.5 inches long and eating inch long earthworms. I'll post more pics of him/her as soon as I can. The set of gills with no pigment are much shorter than the other set. I think I was just imagining that it's sibbling's eyes were lighter, but Pirate is still a stunner.

His whole left side seems to be lighter, as if the pigment cells were distributed lopsided in his early development. Are there any records of chimeric axolotls (individuals formed from fused embryos).

Oh chimeric embryos, that is exciting, well most i know are ones creted in the laboratory. In a certain stage of developement they will fuse two parts of two eggs togethere and axolotl will form. Use to study things like fusing a genetically fatal disorder guy with a heathy one, study of pigmentation, cell ressearch, grafting, etc. I will just say this, the way axolol immune system handles transplants is amazing, if your ever up for a fun read! I do not know of any chimeric axolotls outside of the laboratory. you know that picture of those axolotls with a black head and a white body? Laboratory Chimera from my understanding. |

There is something interesting going on here. Thanks for the pics. fascinating, indeed. Definately appear similar in appearnce to a chimeric creature, but, I do not know how a chimeric individual could be creted in a creature that uses external fetilization. I may lean that it could be exhibiting mosaicsm (two populations of cells with different genotypes in one individual fromone fertilized egg) I am mostly only familiar with this condition in humans. In the lab, mosaicism is studied in Drosophila that i am aware of. Argh starting bio-lab classes is not coming soon enough :P this article is about Endopolyploidy and there is a section of it relating to axolotl discussing mosaics, "chromosomal chimeras" http://www.pnas.org/cgi/reprint/38/12/1073.pdf |

Very interesting, Jacob, I'm glad to see that this guy is healthy and doing well. I can't wait to see him/her as an adult.Umm, axolotls do have internal fertilization. I don't know enough about chimerism to understand exactly how matters. My thought was that there could have been a somatic mutation when the embryo was at the 2-cell stage, resulting in such a half-and-half animal, but I'm sure there are other mechanisms as well. |

The male (who is Pirate Gary's father) belonged to a friend across town, but he's moving out of state and couldn't bring them with, so he sold him to me.

Pirate Gary is pretty spiffy. Chimaerism is alive and well!
