White Mexican axolotl (Ambystoma mexicanum). This animal is a type of aquatic salamander. It is neotenous, meaning that it retains the characteristics of the juvenile of the species into maturity. This is due to its inability through lack of a specific hormone to metamorphose into an adult. Although some axolotls do undergo metamorphosis, this is rare and most retain their aquatic larval form into sexual maturity. The axolotl has gill-like structures on either side of its head. It also possesses lungs and is able to breathe through its skin. The axolotl which is native to Mexico, is a critically endangered species. Photographed in captivity.
