The Axolotl is a species of salamander, closely related to the Tiger Salamander.
The species originates from numerous lakes in Mexico, such as Lake Xochimilco underlying Mexico City. However, as of 2010, wild axolotls are near extinction due to urbanisation in Mexico City and pulloted waters. Axolotls are used extensively in scientific research due to their ability to regenerate limbs.
Axolotls' limbs are underdeveloped and have long, thin digits. Females can be distinguished from males by their wider bodies, which are full of eggs. Axolotls are neotenic, this means unlike many other amphibians they do not develop lungs and take to land and spend their whole life underwater. Many species related to the axolotl are either entirely neotenic or have some neotenic populations.
