I do not know why but after reading this topic I got the urge to have a
T.dobrogicus!

What you said Yahilles was fun, but if you'd like to know the axolotl is that they are as larvae. For these already even in adults keep the aspect of larva, from life without giving the metamorphosis, and that due to any genetic factors that currently do not know specify. If the subject interested you can always search on google Where there was a metamorphosis in axolotl, the one you'll find is similar salamander to other
Ambystoma!
