Ceratophrys is a genus of frogs in the family Ceratophryidae. They are also known as South American horned frogs as well as Pac-Man frogs due to their characteristic round shape, horned brows, and large mouth. The female frog will typically not "chirp" or "croak" as often as males, but does sometimes. Males frequently have spotted chests, and at about a year old, the males develop spots on their "pads" or "fingers". Males will also sometimes have subtle pads on their front legs during mating season, as well as make a sound similar to a cicada to call to their mates. The female frog is also generally larger than the male frog.
