Interesting fact:

The axolotl is actually a kind of salamander, and those things puffing out of its head are actually its gills! You can also eat them deep-fried in a restaurant in Japan and according to Francesco Clavigero who wrote in 1787, "the axolotl is wholesome to eat, and is of much the same taste with an eel. It is thought to be particularly useful in cases of consumption.”
