Even though we axolotls are actually salamanders, some people somehow got into the habit of calling us the "Mexican walking fish." We have a distinct appearance with a wide head, lidless eyes, and a long, tapered tail, as well as four limbs with tiny digits at the ends. The six feathery branches on our head - our most noticeable feature - are external gills for respiration. Probably our most fascinating feature is our ability to heal and regenerate. If we have any nicks or wounds, they will close up without any scar.
