Very cool but yes very much not an axolotl.

An axolotl is a salamander that has evolved neoteny (imagine a frog staying as a tadpole its whole life). It's also specifically adapted to a specific lake system in Mexico City. If it is kept in water under 57°F (14°C) it will die in a few days. They are also extremely sensitive to changes in the water quality or chemistry. It's not clear that this one will even survive after being rescued
