Babyface

When I started blogging, I told myself that I would have to keep a set deadline to make sure I kept it up. I would write one each weekend, and if I didn’t keep it up, I would almost certainly fall into the trap of procrastination. And here I am. I’m going to see if I can manage back into weekend-ly posts. Since this post is for last weekend, I’ll see if I can crank out another post by Sunday night. It’s getting harder than I expected to keep finding Endangered Ugly Things.














However, looking through IUCN’s list of amphibians, I never expected to see this guy. It’s the Axolotl (Ambystoma mexicanum), whose face appears on many “Strange Animals!”-type publications and programs¹. They fall into that category due to the fact that they exhibit neoteny; that is, they never undergo metamorphoses like other amphibians, but retain their gills and dorsal fin for life. They are classified as mole salamanders (genus Ambystoma), which includes more everyday salamanders, such as the Eastern Tiger².

If you think the name “Axolotl” is hard on the mouth, just wait, I’ve got a few doozies in the next paragraph.
The Axolotl likely gets its name from the Aztec words meaning “water-dog,” though some sources link it to the other Aztec god of the underworld, Xolotl, twin of Quetzalcoatl. With these clues (as well as the fact that its species name is mexicanum), it’s not hard to guess where these are generally found in the wild. Yes, it lives in central Mexico, and its historic range includes Lake Xochimilco and Lake Chalco, which hasn’t existed since before the Europeans showed up. Xochimilco (National Geographic pronunciation: SO-chee-MILL-koh) is now only a series of canals within the bounds of Mexico City. Understandably, Axolotl populations aren’t quite what they were when the Aztecs were using them as a daily meat source.

While pollution and habitat loss have thrown the wild Axolotls onto the Critically Endangered list, that isn’t to say that there aren’t many left. They breed in captivity wonderfully, and are used in many medical research labs to study their ability to regenerate limbs (wouldn’t that be convenient?).

The restoration of an ecological park has stabilized populations in the wild, and the introduction of the abundant captive bred individuals could bring these salamanders back from the brink. Also, a local university is working hard to save the local wildlife by increasing public awareness, and are using the Axolotl as their flagship species.

¹I, personally, first came to know of their existence from a series called Zoobooks, where an Axolotl appeared on the cover of “Animal Wonders,” I believe.
²Neat fact: other Mole Salamander species have developed neoteny, which apparently frequently shows up where the water is low on predators and the surrounding land is dry.
