Axolotl always live in the water and likes to eat small fish, worms, and larvae. These animals sometimes appear on the surface of the water, but there is also a mature and grow ahead of never arise in surface water and only stayed in the bottom of the lake during his lifetime.

Axolotl can be found in Lake Xochimilco and Lake Chalco in Mexico. Later, their populations are threatened due to development carried out on the lake which was to prevent seasonal flooding, so the amount of water in the lake to shrink and their habitat disturbed. Fish influx from other areas who introduced human jg cause the population to shrink. Number of axolotl in nature is unknown. But the population is estimated to decline from about 1,500 per square mile in 1998 to only 25 per square mile this year, according to research scientists Zambrano using nets. Long Enterprises International Union for Conservation of Nature enter axolotl in its annual Red List as threatened with extinction. They say these animals could disappear within five years.
