Descrição da espécie
Geographical Origin and Habitat: This critically endangered frog is strictly endemic to the karst limestone formations and caves of the Gigante Islands (Gigante Norte and Gigante Sur) in Carles, Iloilo Province, Philippines. It is found exclusively in highly humid limestone caves and rocky outcrops.
Taxonomy and Genetics: Belongs to the family Ceratobatrachidae and the genus Platymantis. It represents an island-endemic relict population with a tiny distribution area. Like other Platymantis, it utilizes direct development, depositing terrestrial eggs in wet cave crevices.
Behavior and Habits: Strictly nocturnal, troglophilic, and rupicolous. It spends the day hiding in the dark, humid interior of karst caves or deep limestone fissures. At night, it emerges onto rock faces to hunt small cave invertebrates. It is extremely sensitive to habitat changes.
Morphology: A small frog with elongated limbs and expanded digital discs on both fingers and toes, allowing it to navigate slick, vertical rock surfaces. Its skin is finely granular, with a mottled gray-brown-green coloration that blends seamlessly with wet limestone.
Cuidado, criação e companheiros de tanque
Terrarium Setup: Requires a tall, vertically oriented terrarium measuring at least 50x50x80 cm (20x20x32 inches). Create a realistic karst limestone wall with numerous deep fissures and dark retreats. Substrate should be well-drained, topped with wet sphagnum moss.
Lighting and Heating: Provide very dim, shadowed lighting to replicate the cave environment. A 2% UVB lamp should be mounted outside the enclosure. Maintain stable temperatures between 21°C and 24°C (70°F-75°F) with a slight night drop. Avoid any hot basking lamps.
Humidity and Hydration: Relative humidity must be kept at 90% to 95% at all times. Automated misting systems or ultrasonic foggers are mandatory. A dripping system that mimics natural cave walls is highly beneficial for hydration. Do not allow the substrate to dry out.
Feeding and Supplementation: Feeds on small cave-dwelling and terrestrial insects. Offer flightless fruit flies, pinhead crickets, springtails, and isopods. Prey items must be dusted with high-purity calcium and vitamin D3 at every feeding due to the lack of natural sunlight.
Compatibility: Strictly for advanced, single-species terrariums. Keep individually or in carefully monitored breeding pairs. Do not introduce any tankmates of other species to prevent pathogen transmission and avoid causing territorial or calling stress.
Health and Common Diseases: Highly delicate and intolerant of temperature spikes. High risk of chytridiomycosis and bacterial skin infections if tank hygiene is neglected. Dual ventilation is essential to maintain low airflow and prevent stagnant air pockets.

Perfil anfíbio
- Dieta
- Insectivore
- This species is primarily insectivorous in the wild, feeding on a wide variety of small forest invertebrates. In captivity, their diet should consist of appropriately sized crickets, fruit flies, and small worms. It is important to dust the feeder insects with calcium and vitamin supplements to ensure proper nutrition. Feeding them every other day is usually sufficient for adult frogs. Clean, fresh water must be available at all times.

- Estilo de vida/Microhabitat
- Terrestrial
- These amphibians lead a primarily terrestrial and scansorial lifestyle within tropical forest ecosystems. They navigate the complex structure of the forest floor, frequently climbing on small shrubs, roots, and rocks. A heavily planted terrarium with a deep substrate layer best replicates their natural habitat. They thrive in environments with very high humidity and dense vegetation. Consistent environmental conditions are key to keeping them healthy.
- Ciclo de atividades
- Nocturnal
- They are predominantly nocturnal animals, becoming most active after the sun goes down. During the day, they remain well hidden in the damp, shaded parts of the forest floor to avoid desiccation and predators. Once night falls, they emerge to actively forage for small insect prey. Captive environments should mimic this cycle with appropriate lighting periods. A strict day and night cycle is crucial for their overall well-being.
- Socialidade
- Gregarious
- As small forest dwellers, these frogs are generally quite shy and reclusive by nature. They spend the majority of their time hidden among leaf litter, under decaying logs, or in the crevices of low-hanging vegetation. When threatened, they rely heavily on their natural camouflage to blend into the forest floor. They may vocalize during the breeding season with distinct calls to attract mates. Providing ample hiding spots in captivity helps reduce their stress levels.
- Reprodução
- Direct development
- These frogs are known for their unique reproductive strategy, often involving direct development in moist terrestrial environments. Rather than having a free-swimming tadpole stage, females lay eggs in damp leaf litter. Inside the egg capsules, the embryos develop fully and hatch as miniature, fully formed froglets. This adaptation allows them to reproduce without relying on standing bodies of water. Maintaining adequate moisture in the breeding enclosure is strictly required.
- Toxicidade
- Toxic
- No known toxicity to humans, but sensitive to chemical agents on the skin.
- Estágio de vida
- Direct development
- Direct embryonic development: eggs are laid in moist leaf litter and hatch directly into tiny froglets.
- Tolerância de tratamento
- Display only
- Like most small frogs, they have delicate, permeable skin that can absorb harmful oils and salts from human hands. They should be considered a display-only species, with handling strictly avoided unless absolutely necessary for health evaluations or enclosure transfers.
- Brumação
- Não obrigatório
- Hailing from tropical environments, this species does not undergo brumation. They require a consistently warm and highly humid environment year-round, without significant seasonal drops in temperature.
- Muda
- Periodic
- They shed their skin regularly, a process heavily dependent on maintaining high ambient humidity in the enclosure. Shedding happens quickly and discreetly, often at night, and the shed skin is almost always immediately consumed by the frog to recover nutrients.
