The Mexican Axolotl aka The Mexican Walking Fish (Ambystoma mexicanum)
- Found exclusively in the lake complex of Xochimilco
- The Mexican axolotl (pronounced ACK-suh-LAH-tuhl) salamander has the rare trait of retaining its larval features throughout its adult life. This condition, called neoteny, means it keeps its tadpole-like dorsal fin, which runs almost the length of its body, and its feathery external gills, which protrude from the back of its wide head
- This neoteny also means that this species is entirely aquatic
- In rare cases this species will reach its mature stage and leave the water
- This salamander is commonly called the Mexican Walking Fish, however it is an amphibian
- They are typically black or mottled brown, but albino and white varieties are somewhat common, particularly among captive specimens
- Axolotls are long-lived, surviving up to 15 years on a diet of mollusks, worms, insect larvae, crustaceans, and some fish
- They are accustomed to being a top predator in its habitat, this species has begun to suffer from the introduction of large fish into its lake habitat. Natural threats include predatory birds such as herons.Populations are in decline as the demands of nearby Mexico City have led to the draining and contamination of much of the waters of the Xochimilco Lake complex. They are also popular in the aquarium trade, and roasted axolotl is considered a delicacy in Mexico, further shrinking their numbers. They are considered a critically endangered species
- Because they have the ability to regenerate lost body parts, axolotls are probably one of the most scientifically studied salamanders in the world
