  3. The Smile and the Vacuum MouthKids will learn that the axolotl's smile is the shape of its mouth and that it eats by fast suction feeding.The axolotl's cheerful smile is just the curved shape of its mouth, not a real smile. It eats by suction feeding, opening its mouth super fast to slurp food in like a vacuum. Since it can't see well, it finds food by smelling and feeling movements in the water.
  4. One Special Home and How We HelpKids will learn where wild axolotls live, their Aztec legend, and how people help protect them.Wild axolotls live in only one place: the canals of Xochimilco near Mexico City.
