Axolotl's are almost extinct in the wild, because, like the previously featured Texas Blind Salamander, their habitat is being threatened. Due to their natural homes being right next to Mexico City, the 2nd most populated city in the world, their watery homes are being used up and polluted. Interestingly though, they are used extensively for scientific research, and are kept as pets in multiple countries, ensuring that the species won't ever become truly extinct for a very long time, if ever.

Also previously mentioned was their existence as household pets. I am no expert on their captivity requirements, so I'll just redirect to curious to Axolotl.org, which seems to know what they are talking about.
