Editor's note: The earliest known salamander species predates the dinosaurs, and there are around 656 known species remaining. Some are lung-breathers, while many breathe through their skin. Other salamander skills include regenerating lost limbs and being fiercely adorable. One of the cutest of all is Mexico’s Axolotl, which is pedomorphic, meaning it retains its baby features into adulthood (think a puppy who looks like a puppy when it’s grown).
