In the canals beneath Mexico City and in the lake that surrounds it lives the Axolotl or "Water Monster." It is an ancient race of up to 2 ft long salamander that Aztecs say are the direct descendent's of Xototl, the dog headed god of Death. I think they look more like pokemon with their cartoonish eyes and mouths and anime style external gills.
In 1998 the waters of Lake Xochimilco held 1500 axolotl per square mile, when surveyed this year it was a mere 25 per square mile. Scientists are now saying this otherworldly creature may only have five years left on the planet before it succumbs to extinction.
