Question: what is the difference between a horned frog and a horned toad?
Answer: The horned lizard is popularly called a "horned toad", or "horned frog", but it is neither a toad nor a frog. The popular names come from the lizard's rounded body and blunt snout, which give it a decidedly batrachian appearance. Phrynosoma literally means "toad-bodied" and cornutum means "horned".
