Celebrating Lizards

Today is World Lizard Day. From the giant 6-foot-long Komodo dragon, to the teeny-tiny 1-inch-long nano-chameleon, these amazing reptiles live all over the world. There are more than 7000 different lizard species. Chameleons can change color, geckos can walk on ceilings, and basilisks can run on water. Which scaly critter is your favorite?
