Description de l'espèce
Geographical Origin and Habitat: Native to the semi-arid grasslands, scrublands, and seasonal floodplains of the Gran Chaco region spanning Argentina, Bolivia, Paraguay, and Brazil. Unlike rainforest frogs, they spend dry seasons buried deep underground in a protective cocoon of dead skin to conserve moisture.
Taxonomy and Genetics: A stocky, rounded frog reaching 10–15 cm in size. The head is extremely large, making up nearly half of its body, with a wide mouth and small skin horns above the eyes. The "Peppermint" morph features an eye-catching, cool pastel mint-green coloration.
Behavior and Habits: Solitary, inactive ambush predator. They spend their lives buried in the substrate up to their eyes, waiting for prey to walk by. They do not hop; instead, they lunge forward to swallow prey whole. Males emit a loud, cow-like grunt when calling.
Morphology: Sexual dimorphism is pronounced: adult females are massive, circular giants, while adult males are smaller, more slender, and develop dark throats and nuptial pads during the breeding season.
Soins, reproduction et cohabitation
Terrarium Setup: Require a terrestrial horizontal terrarium of at least 60x45x30 cm. Provide a deep, soft substrate (at least 10–15 cm) of moist coconut fiber or organic soil to allow burrowing. Avoid sharp rocks or branches. Include a very shallow water dish.
Lighting and Heating: Keep warm and moderately dry. Maintain daytime temperatures of 26–28°C with a heat spot. Avoid under-tank heating mats, which can cook the burrowing frog; use overhead heating instead. Provide a night drop to 20–22°C. Provide low-level UVB (5%) or keep shaded.
Humidity and Hydration: Maintain moderate humidity of 60–70%. Substrate should be moist like damp forest soil, but never saturated or muddy to prevent deadly bacterial infections (Red Leg syndrome). Mist daily with dechlorinated water.
Feeding and Supplementation: Voracious predators. Feed appropriate-sized live crickets, locusts, roaches, and earthworms. Avoid feeding wild prey to prevent parasites, and limit rodents to prevent obesity. Always use tongs to feed to prevent impaction and painful bites. Dust with calcium and vitamin D3.
Compatibility: Strictly solitary and highly cannibalistic. They must be housed individually at all times. They will attack and eat anything that moves, including other pacman frogs. Never mix with other species.
Health and Common Diseases: Susceptible to ammonia poisoning from their own waste; change the substrate regularly. Avoid handling with bare hands. Watch for signs of Red Leg syndrome, lethargy, or loss of appetite, and maintain strict hygiene.

Profil d'amphibien
- Régime alimentaire
- Carnivore
- Pacman frogs are ambush predators with a massive appetite, eating insects, worms, and appropriately sized rodents. Juveniles should be fed a staple of gut-loaded crickets or roaches, while adults can handle larger prey like nightcrawlers and occasional mice. Dusting food with calcium and vitamins is critical, but avoid overfeeding to prevent obesity.
- Espérance de vie
- 10-15 years
- Taille adulte
- 20 cm
- Mode de vie/microhabitat
- Terrestrial
- Terrestrial and burrowing, they require a deep, moisture-retaining substrate like coconut fiber or sphagnum moss. They do not need a large enclosure but do require distinct moisture and temperature gradients. Provide a shallow water dish that they can easily enter and exit.
- Cycle d'activité
- Nocturnal
- Mostly nocturnal or crepuscular, they remain inactive during the day to avoid desiccation. They will become alert when food is introduced, regardless of the time of day. Their activity is primarily limited to eating and burying themselves.
- Sociabilité
- Gregarious
- They are extremely sedentary, spending most of their time half-buried in the substrate waiting for prey to pass by. They can be aggressive feeders and will lunge at anything that moves near their mouth. They are solitary animals and should be housed individually to prevent cannibalism.
- Reproduction
- Oviparous
- Breeding is difficult in captivity and requires a specific cycling process involving a dry period followed by heavy simulated rain. Males call loudly to attract females to shallow water where amplexus occurs. Females can lay thousands of eggs, and the resulting tadpoles are highly carnivorous and cannibalistic.
- Toxicité
- Harmless
- The Peppermint Pacman Frog is entirely non-toxic and possesses no venom glands. They rely on camouflage and their biting capability for defense rather than chemical deterrents. While their bite can be surprisingly strong and painful due to odontoid projections (tooth-like structures) in their jaw, it is not venomous. Keepers should wash their hands before and after handling or feeding to protect the frog's sensitive skin and maintain good hygiene. They pose no toxic threat to humans or other household pets.
- Stade de vie
- Metamorphosis
- The Pacman Frog begins its life as an aquatic, carnivorous tadpole that requires separation from siblings due to cannibalistic tendencies. Once metamorphosis is complete, the Peppermint juvenile froglet grows extremely fast if fed properly. They reach sexual maturity and near adult size within 10 to 12 months, depending on feeding frequency and temperature. Adult Pacman frogs are large, heavily built, and predominantly sedentary, capable of living 10 to 15 years under optimal care conditions. Throughout their life stages, maintaining proper humidity and substrate moisture is vital.
- Tolérance aux manipulations
- Display only
- Handling of the Peppermint Pacman Frog should be strictly minimized and generally avoided unless absolutely necessary for cleaning or health checks. Their skin is extremely delicate and easily absorbs toxins, oils, or soaps from human hands, which can lead to illness. Additionally, their aggressive feeding response means a moving finger can easily be mistaken for food, resulting in a painful bite. If handling is required, wearing moistened, powder-free nitrile gloves is highly recommended. Scooping the frog gently from behind or using a small container to move them is safer than picking them up directly.
- Brumation
- Non requise
- In the wild, Cranwell's Horned Frogs undergo a period of dormancy known as estivation during the dry season, encasing themselves in a tough cocoon of shed skin to retain moisture. In captivity, this is not strictly necessary for the Peppermint morph unless breeding is intended, and it carries significant risks if not managed correctly. If the enclosure becomes too dry or cold, the frog may enter this state involuntarily. It is safer to maintain consistent, optimal temperatures and humidity year-round to keep the frog active and eating. If estivation occurs, the frog should be slowly rehydrated with warm misting over several days.
- Mue
- Periodic
- The Peppermint Pacman Frog sheds its skin regularly as it grows, a process that happens more frequently in rapidly growing juveniles. The shedding process involves the frog making a series of stretching and wiping motions with its limbs to peel the old skin off its body. It is completely normal for the frog to eat its shed skin, which helps recycle nutrients back into its system. Providing a shallow soaking dish and maintaining proper ambient humidity are essential to ensure the shed comes off cleanly in one piece. Patches of retained shed indicate that the enclosure is too dry and needs immediate adjustment.
