Why does the Mexican Axolotl live in one lake?

The Mexican axolotl (Ambystoma mexicanum) is endemic to Lake Xochimilco, a unique freshwater habitat in Mexico City. This lake's specific environmental conditions, such as its temperature, water chemistry, and availability of food sources, support the axolotl's survival. Additionally, urbanization and habitat degradation have confined this species to this single lake, making it critically endangered and reliant on this limited ecosystem. Conservation efforts are essential to protect their remaining natural habitat.
