A large bodied frog that has an enormously big mouth compared to its legs and front arms. Its name derives from the fleshy horn that protrudes above its eyes. These frogs possess subtle differences compared to that of (C. ornata) including a longer and more sloping snout.
Females tend to be the larger of the two sexes, by up to 4cm in length. Males have a blue to grey throat colouration, with loose skin caused by an external vocal sac. Upon maturity, males will also develop horny nuptial pads on their inner toes.
Temperatures should be maintained around 24°C (75°F) during the day, and with a small night-time temperature drop. Unlike (C. ornata) which live in more tropical regions of South America, once these animals reach adult, they prefer somewhat drier conditions.
