The native habitats of A. mexicanum are large, relatively permanent (until recently), high-altitude lakes located near Mexico City. Of the two lakes - Chalco and Xochimilco - where these animals are historically native, only Xochimilco (elevation: ~ 2,274 m) remains. Axolotls are almost extinct in their native habitat, largely due to the introduction of predatory fishes and habitat loss.
Average elevation: 2290 m.
Habitat Regions: freshwater
Aquatic Biomes: lakes and ponds
