Ceratophrys is a genus of frogs in the family Leptodactylidae, subfamily Ceratophryinae. They are also known as South American horned frogs as well as pacman frogs due to their characteristically large mouth and abdomen, thus resembling the video game character Pac-Man.1

The female will not "chirp", or "croak", whereas a male specimen of the same species will. Males frequently have spotted chests. Males will also sometimes have pads on their front legs during mating season(these are very hard to see though).
In captivity, these frogs can live in a 10 gallon aquarium for their entire lives. They should be given shallow water, loose substrate (like coconut husk fiber), and hiding places. They will commonly cover themselves with substrate or just sit contententedly in the water. Pacmans 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, butterworms, and occasional guppies, mice, and waxworms. Mealworms and superworms should not be fed to them, due to their hard chitinous shell.
The average lifespan of a Pacman frog is about 6 years, but they have been known to live up to 14 years in captivity.
They are voracious eaters, often eating insects, small mammals (such as mice), fish, other frogs, and small reptiles. A fully grown female Argentine Horned Frog (females are generally larger than males) can easily eat a grown rat.
Although these frogs can swallow animals almost half their size, they sometimes attempt to eat things larger than they are. A row of sharp teeth in their upper jaw makes it nearly impossible for them to release prey after taking it in their mouth, in some cases leading to death by choking.

The Ceratophrys has been dubbed with the nickname, "Hypnotoad" seen in various episodes of Futurama.
