Ceratophrys is a genus offrogs in the familyCeratophryidae. They are also known asSouth American horned frogs as well asPacman frogs due to their characteristic round shape, horned brows, and large mouth, reminiscent of thevideo game characterPac-Man.
There are eight species:[1][2]

They have green and brown dorsal coloration.[3]
The female frog will typically not "chirp" or "croak" as often as males, but does sometimes. Males frequently have spotted chests, and at about a year old the males develop spots on their "pads" or "fingers". Males will also sometimes have subtle pads on their front legs during mating season, as well as making a sound similar to a cicada to call to their mates. The female frog is also generally larger than the male frog.
In captivity,C. cranwelli andC. ornata are the most popular species,[4] along with the "fantasy frog", a captive-produced hybrid betweenC. cranwelli andC. cornuta. These frogs can live in a terrarium with a floor area 8-10 times the size of the frog.[4] They commonly cover themselves with substrate or just sit contentedly in the water.
The average lifespan of aCeratophrys frog in the wild varies between 1 and 4 years. In captivity and as pets, depending on diet and care, they may live up to 15 years.[5]
A Pacman frog owner, for example, who offers a roomy and well-kept home, feeds their frog a balanced diet of live insects, and routinely evaluates its health should anticipate their frog to live closer to the higher end of the lifetime range.[6]
They are voracious eaters, often eatinginsects, small mammals (such asmice),fish, otherfrogs, and smallreptiles.[7] A fully grown femaleArgentine Horned Frog (females are generally larger than males) can easily eat a grownrat. They aresit and wait predators.[3]
These frogs are also known to be cannibalistic, and have been known to eat their mates, even if they are larger than they are.
Although these frogs can swallow animals almost half their size, they sometimes attempt to eat things larger than they are. Their teeth, as well as bony projections in the front of the jaw, can make it difficult for them to release prey after taking it in their mouth, in some cases leading to death by choking.
They have a very sticky tongue which they use to catch prey and pull it into their jaws.[8]
Large individuals have bite forces comparable to those of mammalian predators.[9]
