Ambystoma mexicanum (Axolotl)

Language: Spanish

Wikipedia Abstract

The axolotl (/ˈæksəlɒtəl/, from Classical Nahuatl: āxōlōtl [aː.ˈʃóː.loːtɬ]) also known as a Mexican salamander (Ambystoma mexicanum) or a Mexican walking fish, is a neotenic salamander, closely related to the tiger salamander. Although the axolotl is colloquially known as a "walking fish", it is not a fish, but an amphibian. The species originates from numerous lakes, such as Lake Xochimilco underlying Mexico City. Axolotls are unusual among amphibians in that they reach adulthood without undergoing metamorphosis. Instead of developing lungs and taking to land, the adults remain aquatic and gilled.

EDGE Analysis

The name “axolotl” is thought to have originated from the Aztecs, derived from two words: atl, meaning “water”, and xolotl meaning “monster”. Axolotls do not develop adult characteristics but retain their gills, fins and other larval characteristics throughout their life. They live permanently in water, in the wetlands and canals associated with Lake Xochimilco and Lake Chalco, adjacent to Mexico City. Once eaten as a delicacy in Mexico City, they are now a protected species in Mexico and Critically Endangered in the wild.
