Sure! Axolotls are super cool :D
First of all, you should know the morphs we have bred in captivity are not comparable to the wild Axolotls - they were crossbred with tiger salamanders to introduce the albino gene.
So with that in mind, first we have the wild-type! (not to be confused with an actual wild Axolotl! These are still captive-bred, they just LOOK like how the wilds look).
Wildtypes are olive colored and spotty, and can have shiny pigments (iridiophores).
Then we have Melanoid Axoltols! http://en.wikipedia.org/wiki/Melanism
Melanoids are darker, and you can tell them from wildtypes by the fact that wildtypes have that shiny ring in their eye, and melanoids don’t. They also lack iridiophores.
Then we move on to the popular pink Leucistic. http://en.wikipedia.org/wiki/Leucism
They are pink with black eyes!
Not to be confused with the Albino Axolotl!
They have those pink/red albino eyes! (Every time I search ‘Albino axolotl’ a bunch of leucistic ones come up - nope! incorrect!)
We also have Golden Albino Axolotls, which my Zion here demonstrates
He has the albino eyes, he’s just very gold! It should be noted most golds are darker than zion is - he’s a pretty pastel boy. They can get pretty dark orange looking.
There are a few other rare mixes of these - such as piebald or melanoid albino (You would think that wouldn’t be possible) but they’re hardly worth mentioning as they’re so rare.
The other thing is chimerism happens sometimes!
(and holy butts let me tell you how much I WANT A CHIMERIC AXOLOTL. Chimerism deeply fascinates me and it is my dream to have a chimeric lotl. so PS any lotl breeders out there if you happen to get a chimeric, I will pay top dollar just throwing that out there)
Another thing to note is GFP Axolotls - Glowing fluorescent protein. Basically these are Axolotls (of any color morph) that are bred/genetically modified to have certain jellyfish proteins in them that glow under a blacklight. this was done so SCIENTISTS could view tissue regeneration under blacklight.
When not under blacklight, the protein gives them a weird greenish hue.
in my opinion, these have no place in the pet trade. They were originally created for scientific purposes, and putting the animal under a blacklight is cruel to them; it has been documented that they see the UV spectrum and the light distresses them. Plus it makes their eyes themselves glow. So again, no place in the pet trade for people who just want them because ‘lol my pet glOWS in the DARK’ which isn’t even accurate.
So there’s my rant on Axolotl morphs, anon!
