Horned lizard Horned lizard Horned lizards (Phrynosoma), also known as horny toads or horntoads, are a genus of North American lizards and the type genus of the family Phrynosomatidae. The common names refer directly to their flattened, rounded body and blunt snout. The genus name "Phrynosoma" means "toad-bodied". In common with large true frogs and toads, horned lizards tend to move sluggishly, making them easy to catch; this may also avoid triggering attacks by predators. They are adapted to arid or semi-arid areas. The spines on the lizard's back and sides are made from modified reptile scales which prevent the water loss
Boettger's horned toad Tadpoles are in length. Boettger's horned toad Boettger's horned toad, Boettger's spadefoot toad, or pale-shouldered horned toad (Xenophrys boettgeri), is a species of toad found in southern and southeastern China (the northern border runs roughly from Sichuan in the west to Shanxi in the north and Zhejiang in the east) and northeastern India (Arunachal Pradesh, Sikkim, and Assam). A closely related but probably as yet undescribed species in found in Tibet. It is not certain that the Indian specimens belong to "Xenophrys boettgeri" either. The history of this species' discovery is highly international. It was described by George Albert Boulenger,
