The Argentine horned frog is also commonly known as the Argentine wide-mouthed Frog or Pacman frog, and is the most common species of horned frog. It is native to the rain forests of Argentina but can now be commonly found throughout Argentina, Uruguay and Brazil.

The Argentine horned frog is most well known for being a voracious eater, as the horned frog will attempt to swallow anything that moves close to the horned frogs wide mouth. It tends to hunt things such as insects, small birds and mammals, lizards and other frogs, and it is often very greedy with its selection.

The Cranwells horned frog is also originally from Argentina but is hard to find elsewhere as the Cranwells horned frog is an extremely popular exotic pet particularly in North America. This is because the horned frog is a very hardy species of frog, making the horned frog one of the easier exotic pets to look after.
