A Cute Amphibian
The Mexican axolotl salamander is a distinct amphibian since it retains its larval features all through adulthood. This condition is called neoteny, which means it keeps its tadpole-like dorsal fin that runs almost the length of its body, and its feathery external gills, which protrude from the back of its wide head.
This rare species is found exclusively in the lake complex of Xochimilco, near Mexico city. The axolotl differs from other amphibians since it spends its entire life in the water, mostly at the bottom of the lake. On rare occasions, an axolotl will come out of the water once it has matured.
Since the Mexican axolotl is a close relative of the tiger salamander, it can get quite big, reaching up to a foot in length. Most of these species are black or mottled brown, but albino and white varieties aren’t uncommon in captive environments.
