A beautifully camouflaged Horned Toad (Phrynosoma cornutum) basks in the morning sun in Catalina State Park near Tucson, AZ. The misnamed Horned Toad is not a toad but is a member of the lizard family. The popular name comes from its rounded body and blunt snout, which give it a decidedly toad-like appearance. Phrynosoma literally means "toad-bodied," and cornutum means "horned". Its horns are extensions of its cranium and contain true bone.
