Where do axolotls live in the wild?

The axolotl is a salamander that once lived in two high-altitude lakes in the Valley of Mexico, Xochimilco and Chalco. Lake Chalco was drained, so today the species survives in the wild only in the remaining canals of Xochimilco. It is listed as Critically Endangered because of pollution, urban growth and introduced fish such as carp and tilapia. Surveys found wild numbers fell from around 6,000 per square kilometre in 1998 to about 36 per square kilometre in 2014. Axolotls are famous for keeping their larval features, such as feathery gills, as adults and for regrowing lost limbs and even parts of organs.
