Ceratophrys cranwelli

Cranwell's horned frog (Ceratophrys cranwelli), also called the Chacoan horned frog, is a terrestrial frog endemic to the dry Gran Chaco region of Argentina, Bolivia, Paraguay and Brazil.
Like most members of the genus Ceratophrys, they are often considered Pacman frogs because of their resemblance to the popular video game character of the same name. Most adult species range from 8–13 cm long and can weigh up to 0.5 kg.
Endemic of Argentina, Bolivia, Paraguay and Brazil.
They are ordinarily carnivorous, feeding mostly on insects and like-sized animals, and are known to cannibalize other frogs.
