Axolotl

This fella almost looks like some strange fantasy creature, doesn't he? He's called the Mexican Salamander or the Tiger Salamander.

"Ordinarily, amphibians undergo metamorphosis from egg to larva (the tadpole of a frog is a larva), and finally to adult form. The Axolotl, along with a number of other amphibians, remains in its larval form throughout its life. This means that it retains its gills and fins, and it doesn't develop the protruding eyes, eyelids and characteristics of other adult salamanders."
