Ambystoma mexicanum axoltl

Native of the lakes of Mexico City, axolotl is the most famous amphibious in science. The axoltotl salamander’s peculiarity is that it keeps all life long its larval characteristics. This condition is called neoteny, and the animal can reproduce itself keeping the physical characteristics of the larva. The external gills are feathered and stick out of its head, and the spine, similar to a tadpole, runs almost to the length of its body. Usually they are brownish mottled color, but the albino and white ones are quite common, particularly between the specimens in captivity. Axolotl unlike the other salamanders lives permanently in water. In some rare cases the axolotl can bring its body to full maturity rising out of water.
