Description de l'espèce
Geographical Origin and Habitat: Native to the semi-arid Gran Chaco region of Argentina, Bolivia, Paraguay, and Brazil. Unlike rainforest frogs, they inhabit dry savannas and scrublands, spending dry seasons buried underground in a cocoon of dead skin cells to prevent dehydration.
Taxonomy and Genetics: A member of the Ceratophryidae family, popular as the Pacman Frog due to its round body and massive mouth. The 'Pikachu' morph is selectively bred for its intense, solid bright-yellow coloration, which mimics the famous cartoon character. It reaches up to 15 cm in length.
Behavior and Habits: A sedentary, burrowing ambush predator. They spend almost their entire life buried in the substrate, waiting for prey to pass. They do not jump or climb, but crawl slowly. Males emit a loud, bark-like mating call during seasonal rains.
Morphology: Females are much larger, rounder, and heavier than males. Males are smaller, develop dark coloration on their throats, and have nuptial pads on their thumbs during the breeding season.
Soins, reproduction et cohabitation
Terrarium Setup: Requires a horizontal terrestrial enclosure (minimum 45x45x30 cm). Provide a deep (10-15 cm) substrate of damp coconut fiber or peat moss to allow burrowing. Do not include climbing branches or rocks. A very shallow water dish is required, as they are poor swimmers.
Lighting and Heating: Requires warm temperatures between 26 and 28°C during the day. Do not use under-tank heating mats, as they will overheat the frog; place heating mats on the side of the terrarium. Provide low-intensity lighting with a 5% UVB source.
Humidity and Hydration: Maintain moderate humidity levels between 60% and 70%. Avoid waterlogged, muddy substrate, which fosters bacterial skin infections. Mist the enclosure daily with declorinated water, ensuring good ventilation to keep the air fresh.
Feeding and Supplementation: Highly voracious. Feed on crickets, roaches, earthworms, and occasional feeder fish or mice. To prevent impaction from swallowing substrate, feed them using tongs. Dust prey with calcium and vitamin D3 supplements three times a week.
Compatibility: Strictly solitary and cannibalistic. They will consume any tankmates, including other Pacman frogs of similar size. They must always be housed individually.
Health and Common Diseases: Prone to toxicosis and red leg syndrome from dirty substrate; change the soil regularly. Avoid handling to prevent damaging their sensitive skin, and beware of their strong bite, as they have sharp odontoid projections in their jaws.

Profil d'amphibien
- Régime alimentaire
- Carnivore
- The diet of Ceratophrys cranwelli "Pikachu" consists mainly of appropriately sized prey or specific plant matter, depending on its natural biology. Providing a varied and nutrient-rich diet is essential for maintaining their immune system and overall health. Owners must ensure that all food items are properly dusted with high-quality calcium and vitamin D3 supplements to prevent severe metabolic issues. Fresh, clean water should also be accessible at all times to aid in digestion.
- Espérance de vie
- 10-15 years
- Taille adulte
- 15 cm
- Mode de vie/microhabitat
- Terrestrial
- Adapting uniquely to their environment, Ceratophrys cranwelli "Pikachu" exhibits a lifestyle that necessitates specific terrarium setups to thrive in captivity. Whether climbing, burrowing, or dwelling on the forest floor, their habitat must replicate the structural elements they utilize in the wild. Proper gradients of temperature and humidity are also essential to support their physiological processes. A well-enriched environment will significantly improve their quality of life and longevity.
- Cycle d'activité
- Nocturnal
- The activity pattern of Ceratophrys cranwelli "Pikachu" is closely tied to its natural habitat's lighting and temperature cycles. They tend to have specific peak hours of activity during which they hunt, forage, and explore their environment. Providing a consistent and naturalistic light cycle with appropriate UVB lighting is critical for regulating their circadian rhythms. During their resting periods, they will seek out secure hides to remain undisturbed.
- Sociabilité
- Gregarious
- Ceratophrys cranwelli "Pikachu" displays a range of fascinating behaviors that are deeply rooted in their evolutionary adaptations for survival. They can be territorial, especially among males, so appropriate enclosure sizing and solitary housing are often recommended to prevent stress and injury. They utilize complex body language to communicate with other members of their species and to deter potential threats. Observing these natural behaviors in a well-designed terrarium is highly rewarding for keepers.
- Reproduction
- Oviparous
- Breeding Ceratophrys cranwelli "Pikachu" generally requires carefully controlled environmental parameters such as temperature and humidity cycling to stimulate natural reproductive behaviors. Females will often need an increase in calcium intake to safely produce and lay healthy clutches of eggs. Once laid, eggs must be promptly moved to an incubator set to the precise temperatures required for optimal development. Careful monitoring of both the breeding adults and the incubating eggs is crucial for successful reproduction.
- Toxicité
- Harmless
- Cranwell's horned frogs completely lack any skin toxins or poisonous physiological secretions. Their primary defense relies entirely on remarkable camouflage to completely avoid visual detection. Their only potential danger to handlers is a painful bite from powerful, tooth-lined jaws.
- Stade de vie
- Adult only
- Their rapid lifecycle starts with eggs hatching into muscular and voracious aquatic tadpoles. Metamorphosis is remarkably fast and usually fully completes within just 3 to 5 weeks. Terrestrial froglets immediately begin eating large insect prey and grow at astonishing rates.
- Tolérance aux manipulations
- Display only
- Pacman frogs possess highly sensitive skin that absorbs harmful chemicals and natural human oils. Handling should be strictly minimized to prevent extreme stress and severe health issues. They are very prone to biting handlers due to their aggressive feeding responses.
- Brumation
- Non requise
- They naturally undergo a period of estivation during harsh dry seasons in native scrublands. They survive by burrowing deep into the earth and encasing themselves in shed skin cocoons. In warm and well-watered captivity, they remain active year-round without needing estivation.
- Mue
- Yes
- They regularly shed their epidermal layer to maintain healthy skin and remove external parasites. The frog performs exaggerated stretching and wiping motions with its legs to loosen old skin. They continuously push the molted skin toward their mouth and swallow it.
