Several species of Horned frog are available as pets, the most common being the Argentine Horned frog. They are, predictably, native to Argentina but are also found in parts of Uruguay and Brazil too. These frogs are also sometimes called Pac man frogs because of their comparatively wide mouth, making them similar in appearance to the computer game character from the 1980s.
Female Argentine Horned frogs grow to be larger than their male counterparts, although it is difficult to determine the sex of a horned frog until they reach maturity. Females can grow to around 15cm whereas males rarely reach 12cm. With the correct care these frogs can live to 10 years or more.
