ANIMAL OF THE DAY: Axolotl (Ambystoma mexicanum)

A type of Mexican mole salamander, larvae fail to undergo the metamorphosis stage of transformation and so retain juvenile characteristics (known as 'neoteny'). They are used extensively in scientific research as they are able to regenerate body parts. It is only native to Lake Xochimilco and Lake Chalco in central Mexico, although Lake Chalco no longer exists as it was artificially drained to avoid flooding. They are critically endangered in the wild and are protected by the Government of Mexico. They are kept as pets all over the world.
