Weird Fish This Week

This week, the top animal is the Axolotl.

Sometimes they get called Mexican walking fish. I bet it’s because it’s way easier than axolotl.

Axolotl, aren’t actually fish though. They’re salamanders, which are amphimbians. That said, they don’t do metamorphoses like other amphibians. You probably know that frogs start as tadpoles and then turn into adult frogs that have lungs. Axolotl don’t do that. They never grow lungs, basically they don’t turn into adults. They stay young their whole lives, just swimming around having a good time.

Axolotl are native to only one place on earth. The lakes around Mexico City. Unforutnately, Mexico City is so big that the urban growth has seemingly annihilated the native population. If you went looking in those lakes, you probably wouldn’t see any of these little guys.

Because they’re so cute, people are also snatching them up as exotic pets and some other people think they look good to eat, so they do it.

Because of all that, axolotl are pretty endangered. In a few years they’ll probably be extinct in the wild. Hopefully all the people keeping them as pets can keep them from going extinct altogether.

Probably the coolest thing about axolotl is that they can regrow basically any part of their body. Not just a lost tail or leg like you see in some other lizard-looking animals, but like jaws and spines and stuff. Some people say they can even regrow parts of their brain.

Axolotl also have a tonne going on in their biology. The axolotl’s genome is 10 times bigger than what humans have. Somewhere in there is the genes for regenerating any part of your body, but there is also other stuff. They’ve got a handful of genes that control what colour they are. In the wild they’re pretty brown or black, but given enough time breeders can get some wild colouration.

One thought on “Weird Fish This Week

  1. A comprehensive post on Axolotl. What about your own insight? Do you think they are significant? Why or why not? Do you think they would make good pets? Should we start hunting them? Is that legal? Do you think it should be legal? What are YOUR opinions, rather than their facts? 🙂
