Axolotl
Animal Overview: The axolotl, also known as the Mexican walking fish, is a type of salamander that retains its larval features throughout its life, a phenomenon known as neoteny. This gives it a unique, almost otherworldly appearance with feathery gills and a smiling face.
Habitat and Behavior: Native to lakes underlying Mexico City, the axolotl is critically endangered in the wild. These creatures are known for their remarkable ability to regenerate lost body parts, making them a subject of scientific interest.
