The WWF refers to Axolotl as the “Peter Pan of Salamanders.” They mostly retain their aquatic larval stage throughout their lives, making their larvae resemble miniature versions of the adults. They do get bigger, and reach up to one foot. In regards to this extremely unique species, “Axolotls were named after Xolotl, the Aztec god of fire and lightning, who could take on the form of a salamander. Xolotl was also associated with dogs, and “all” is the ancient Aztec word for “water”—so “axolotl” is sometimes translated as “water dog.” They don’t do as well in the wild as they do in captivity. They’re also able to regrow their body parts, including their brain, heart, and spine, and can accept body parts from other axolotl without risking rejection (World Wildlife).
