The Argentine Horned Frog (Ceratophrys ornata), also known as the Argentine wide-mouthed Frog or Pacman frog,
is the most common species of Horned Frog, from the rain forests of Argentina, Uruguay and Brazil. A voracious eater, it will attempt to swallow anything that moves close to its wide mouth, such as insects, and rodents, lizards and other frogs, even if it would suffocate in the process.
