Ceratophrys is a genus of frogs in the family Ceratophryidae. They are also known as South American horned frogs as well as Pacman frogs due to their characteristic round shape and large mouth, reminiscent of the video game character Pac-Man.

In captivity, C. Cranwell, C. ornata and C. cornuta are the most popular species, along with the “fantasy frog”, a captive-produced hybrid between C. Cranwell and C. cornuta. These frogs can live in a 10-gallon aquarium for their entire lives. They thrive best with a shallow bowl of water, loose moist substrate (like coco coir), and hiding places. They will commonly cover themselves with a substrate or just sit contentedly in the water. These frogs should be misted daily to ensure proper humidity. Temperatures should be maintained between 75° and 80° Fahrenheit (24° to 27° Celsius) during the day, dropping a few degrees at night. They can be fed crickets, earthworms, silkworms, phoenix worms, butter worms, and occasionally guppies, mice, and waxworms. Mealworms and super worms should not be fed to them, due to their hard chitinous shell.

The average lifespan of a Ceratophrys frog in the wild varies between 1 and 4 years, though in captivity and as pets, depending on diet and care, they may live 6 to 10 years and even longer.
