The axolotl (Ambystoma mexicanum,) is a unique species of mole salamander that displays neotony as it never fully matures and physically resembles a tadpole. While permanently remaining in a larval state, this amphibian fails to metamorphose and, instead, remains aquatic for the entirety of its life. This species is listed as “Critically Endangered” by the IUCN Red List of Threatened Species and can only be found in the deep brackish waters off the southern edge of Mexico City. Although endangered in the wild, the axolotl makes a popular pet and can be found in a variety of colorations.
