What is the six things on an axolotls head?

An axolotl's head features several distinctive structures: two pairs of external gills, which resemble feathery appendages and aid in respiration; a pair of eyes without eyelids; a broad, flat head; and a mouth that is slightly curved. The external gills are particularly notable as they can vary in color and are a key characteristic of this aquatic salamander. Additionally, axolotls have sensory structures called "lateral line" systems along their heads, aiding in detecting vibrations and movement in the water.
