Morphological differences between A. mexicanum and A. tigrinum paedomorph?

[justin]

What are some differences between these two species? A friend of mine bought a "Tiger Newt". She thinks it is a Axotlol...whatever the spelling is. I think t is a paedomorphic Tiger Salamander. By the way this was purchase by a "breeder" in KY.

The salamander in question is dark green in color and has some spots of dark green. It has a pretty decent sized gill structure too. Whaat do you think?

My area of knowledge lies in reptiles, but I am somewhat knowledgable with amphibs. Just curious.
