Pacman Frog
Ceratophrys ornata
On This Page▾
🌍 Overview
The ornate horned frog - nicknamed the Pacman frog for its enormous, round, gaping mouth - is native to the grasslands and rainforests of South America. They are ambush predators that bury themselves in soil or leaf litter and wait, motionless, for prey to enter range of their enormous mouth. Despite their sluggish lifestyle, Pacman frogs will attempt to consume prey nearly as large as themselves - including other frogs, rodents, and small snakes.

📜 History
The species entered science through Darwin's voyage. Thomas Bell described it in 1843 as Uperodon ornatum, in the reptiles volume of the Zoology of the Voyage of H.M.S. Beagle, from a specimen labeled Buenos Ayres, with syntypes catalogued at the British Museum; the genus Ceratophrys, where it eventually landed, had been erected by Wied-Neuwied in 1824. Modern keeping rests on two species rather than one, since Cranwell's horned frog, Ceratophrys cranwelli, is bred and sold alongside the ornate. Breeders also cross Ceratophrys cranwelli with the Surinam horned frog to produce the captive hybrid marketed as the fantasy frog.

🤓 Did You Know?
Pacman frogs (horned frogs, genus Ceratophrys) have an extraordinarily powerful bite for an amphibian. A 2017 study measured Cranwell's horned frogs biting at up to about 33 newtons, and the authors' scaling estimate puts the largest living horned frogs close to 500, the range of medium-sized mammalian carnivores. They will attempt to eat anything that moves near them, including other frogs, small mice, and keepers' fingers.
