What kind of skin does Mexican walking fish have?

Mexican walking fish, also known as axolotls, have smooth, moist skin that is typically a pale pink or white color, often with a translucent appearance. Their skin is covered in a mucous layer that helps keep them hydrated and protects against pathogens. Additionally, they possess external gills that are feathery and protrude from the sides of their heads, enhancing their aquatic respiration. This unique skin structure is well-adapted to their aquatic environment.
