A little damp, very welcome.
Pacman Frog
Ceratophrys ornata
Also called Argentine horned frog, Ornate horned frog, Argentine wide-mouthed frog, Ornate pacman frog, Ornate horned toad
From South America: the grasslands (pampas) of Argentina, Uruguay and southern Brazil.1
At a glance the quick version
Looks how to spot one
Round, wide-bodied ground frog
Almost as wide as it is long, with an enormous mouth, small horn-like points above the eyes and short, unwebbed back legs. Females (up to about 16.5 cm snout to vent) are noticeably bigger than males (about 11.5 cm). Mature males have darker throats.12
Personality what they are like
A patient ambush hunter that sits still, often half-buried, and lunges at anything that moves in front of its mouth. It is a frog to watch rather than handle, as it may grab at fingers and can give a painful bite.12
Daily activity how busy a day looks
Low. It spends most of its time sitting quietly, either dug into soft substrate or soaking in water, and moves mainly to catch food.2
Grooming and care the hands-on bits
Keep handling to a minimum and provide a soft, diggable substrate plus a water dish shallow enough for it to sit in, since it is a poor swimmer.21
Home where they are happiest
A floor-focused terrarium: Wikipedia suggests a floor area about 8-10 times the frog's own footprint. Include soft substrate deep enough to burrow into and a shallow water area.2
Food basics what goes in the bowl
Carnivorous. In the wild it eats insects, spiders, other frogs, small reptiles and small mammals and birds. In captivity, young frogs are typically fed crickets and adults earthworms, with occasional fish for variety.12
Company who they like around
Keep singly. Horned frogs will try to eat tankmates, including their own kind.21
The story where it all began
A native of the South American pampas, this frog became a popular exotic pet, and its round body and huge mouth earned it the nickname 'pacman frog' after the arcade game character. Captive breeding has produced several colour forms, including albinos, and related horned frog species are crossed to make hybrids such as the 'fantasy frog'.12
Fun facts for the dinner table
- 1
Its pacman nickname comes from the arcade game, thanks to its round shape and giant mouth.1
- 2
It will try to swallow prey that is bigger than itself.1
- 3
Large horned frogs have a bite force comparable to mammal predators.2
- 4
Short, unwebbed back legs make it a clumsy swimmer, so it sits in shallow water rather than swimming.1
- 5
Male horned frogs make cicada-like calls in the breeding season.2

Owner questions the things everyone asks
How often should I feed my Pacman Frog?
Feeding frequency depends on the frog's age and size. Young frogs are typically fed daily or every other day, while adults may eat every few days. Furry Diary's starting plan suggests feeding based on species and age, so check with your vet for a schedule tailored to your frog.12 Pet Wiki plan
What does a Pacman Frog eat, and what should it never eat?
Your Pacman Frog is carnivorous and in captivity can eat crickets for young frogs and earthworms for adults, with occasional fish for variety. Never feed it anything that could be too large or cause impaction, and avoid wild-caught prey that may carry parasites; always ask your vet for safe options.12
How much space does a Pacman Frog need?
A floor-focused terrarium is best, with a floor area about 8 to 10 times the frog's own footprint. Include soft, diggable substrate deep enough for burrowing and a shallow water area, as they are poor swimmers.2
What temperature, light or water does a Pacman Frog need?
Provide a warm, humid environment with a shallow water dish of dechlorinated water for soaking. Furry Diary's plan includes daily misting to keep humidity up and daily temperature checks. For exact temperature ranges, consult a vet who sees exotic pets.2 Pet Wiki plan
How often should I clean a Pacman Frog's home?
Spot-clean the enclosure every two days to remove waste and uneaten food. A full clean is recommended every 30 days, as per Furry Diary's starting plan. Pet Wiki plan
Can a Pacman Frog live with others?
No, Pacman Frogs should be kept singly. They are known to try to eat tankmates, including their own kind, so it is safest to house them alone.12
How long does a Pacman Frog live?
With proper care, a Pacman Frog can live between 6 and 15 years. Providing a good habitat and diet helps support a long, healthy life.12
Can I handle a Pacman Frog?
Handling should be kept to a minimum because they may grab at fingers and can give a painful bite. This is a frog to watch rather than handle, so enjoy observing it from a distance.12
