The animal described is the axolotl (Ambystoma mexicanum). The axolotl is a type of salamander native to Mexico, particularly found in the ancient lake complex of Xochimilco. It is most famous for its neotenic characteristics, meaning it retains its larval features throughout its life, including external gills, finned tail, and feathery external gills. Axolotls have a unique ability to regenerate lost body parts, such as limbs, organs, and even parts of the brain and spinal cord, making them a subject of scientific interest and a popular choice in the pet trade. They primarily feed on small prey like worms, insects, and small fish. Despite their remarkable regenerative abilities, axolotls are considered critically endangered in the wild due to habitat loss, pollution, and the introduction of invasive species. Efforts are being made to conserve and protect wild axolotl populations.
