Picture a plump frog sitting perfectly still among the fallen leaves of a forest floor, its mouth so wide it seems to make up half of its body. Meet the Pacman frog. Also known as the Argentine horned frog or ornate horned frog (Ceratophrys ornata), it is one of South America’s most curious creatures. We covered the wider world of these amphibians on our frog page; here, we take a closer look at the family’s hungriest member.
How Did It Get Its Name?
It doesn’t take much guessing. With a round body and an enormous mouth ready to swallow almost anything that fits, this frog bears a striking resemblance to the hero of the legendary 1980s arcade game Pac-Man. Its mouth can stretch to nearly half of its body length, which is a remarkable ratio even by frog standards.
And the “horned” part? Look just above its eyes and you’ll spot fleshy projections that resemble little horns. They aren’t weapons; they’re soft extensions of skin. But once the frog buries itself among dry leaves, those horns make it almost impossible to tell apart from a leaf.
What Does It Look Like?
Pacman frogs are stout, short-legged animals with remarkably broad heads. Females are visibly larger than males and can reach around 16 centimetres. Their colours are a show in themselves: vivid green scattered with red, orange, and brown markings. Better still, no two individuals share the same pattern; each frog carries its own design.
Where Does It Live?
Its home is South America, particularly the humid lowlands and forest floors of Argentina, Uruguay, and southern Brazil. Unlike most frogs, it spends its life on land rather than in water, and it is happiest half-buried in moist soil, waiting.
When the dry season arrives, the species reveals its most surprising trick: it wraps itself in a protective cocoon made of its own shed skin and slips into a months-long dormancy until the rains return. Once the soil softens, it sheds the cocoon and simply carries on.
What Does It Eat, and How Does It Hunt?
The Pacman frog is a textbook ambush predator. It conceals itself partially in the leaves and soil of the forest floor and remains motionless for hours on end. When an unlucky animal wanders within range, the frog strikes in a fraction of a second and usually swallows its prey whole.
The menu is generous, too: large insects such as locusts, worms, big spiders, small reptiles, and even rodents. It doesn’t hesitate to attack prey close to its own size, which is why animal lovers sometimes call it a “walking stomach”.
How Long Does It Live?
In the wild, its average lifespan is around 6 to 7 years. Under human care, with regular feeding and the right humidity, it can comfortably pass the 10-year mark. So if you visit an aquarium and spot a Pacman frog, there’s a fair chance you’ll find it in the same corner years later.
Does It Bite? Is It Poisonous?
It is not poisonous, so rest easy. Its jaws, however, are unusually powerful for a frog, and its mouth carries hard, tooth-like projections. If it mistakes something moving for prey, or feels threatened, it will bite, and that bite is not to be taken lightly. That’s why nobody handles a Pacman frog; watching one, on the other hand, is a real pleasure.
Fun Facts About the Pacman Frog
- It holds one of the widest mouth-to-body ratios in the entire frog world.
- The “horns” above its eyes are camouflage tools, not weapons.
- In dry periods it can build a cocoon from its own skin and stay dormant for months.
- Its patterns are like fingerprints; no two frogs look exactly alike.
- Even the young are fierce predators, and a hungry one may eat its own sibling.
