Axolotl
The axolotl or Mexican salamander (Ambystoma mexicanum) is a neotenic salamander, closely related to the Tiger salamander. Larvae of this species fail to undergo metamorphosis, so the adults remain aquatic and gilled. It is also called ajolote [ɑːhɒˈlɔte] (which is also a common name for different types of salamander).[1] The species originates from numerous lakes, such as Lake Xochimilco underlying Mexico City.[2] Axolotls are used extensively in scientific research due to their ability to regenerate limbs.

As of 2010, wild axolotls are near extinction[3] due to urbanization in Mexico City and polluted waters. Nonnative fish such as African tilapia and Asian carp have also recently been introduced to the waters. These new fish have been eating the axolotls’ young, as well as its primary source of food.[4] The axolotl is currently on the International Union for Conservation of Nature’s annual Red List of threatened species.[5]
