Who's that Pokémon?!

Axolotl

Ambystoma mexicanum

It seems like evolution took a break and forgot to get back to working on the Axolotl. Unlike other amphibians, like frogs and toads, axolotls never grow out of their larva stage. Where frogs and toads would come out of the water and loose their tails, axolotls decided that they weren't about that life and decided they would keep their tails and stay in the water. Originally, axolotls were found only in the lakes of Xochimiloc near Mexico City. Like all cool animals on the planet, axolotls are and endangered species in the wild, thanks to the growth of Mexico City. The waters where axolotls were once found have become so polluted that recent a study say that there might not be anymore axolotls living there. The only reason they are not extinct is because people like to keep them as pets and scientists are studying them for their magical properties. (They regrow lost limbs.)

Axolotls' favorite food is worms. They'll also eat small fish and such since they're carnivorous. The grow up to around 23 cm, commonly. Those fuzzy things around its head are its gills, they help it breath underwater. So yeah, this little guy is pretty cool. For all your axolotl needs.
