Palau island frog
Cornufer pelewensis
A unique terrestrial frog endemic to the Palau archipelago. Lacking an aquatic tadpole stage, it requires a humid forest terrarium and small live food items.

Descrição da espécie
Geographical Origin and Habitat: Endemic to the islands of Palau in the western Pacific Ocean. Inhabits tropical rainforest floors, limestone forest areas, damp gardens, and moist disturbed habitats rich in leaf litter.
Taxonomy and Genetics: Previously classified under the genus Platymantis, now belongs to the family Ceratobatrachidae, genus Cornufer. Characterized by direct embryonic development (hatching directly as fully formed froglets, bypassing the free-swimming tadpole stage).
Behavior and Habits: Primarily nocturnal and terrestrial. Spends daytime hiding under leaf litter, rotten logs, or damp rock crevices. Males emit a characteristic mating call resembling a metallic clicking sound at night.
Morphology: Small frog, with adult males measuring about 2.5-3 cm and females slightly larger (up to 4 cm). Skin is textured with longitudinal skin folds. Coloration is highly cryptic, ranging from gray to dark brown with irregular patterns.
Cuidado, criação e companheiros de tanque
Terrarium Setup: Requires a forest-type enclosure (bioactive recommended) measuring around 45x45x45 cm for a small group. The substrate should consist of organic forest soil or coco fiber topped with a thick layer of leaf litter and sphagnum moss to retain moisture.
Lighting and Heating: Does not require strong lighting; a low-intensity LED for live plants is sufficient. Keep temperature stable between 22°C and 26°C during the day, with a slight drop at night. Avoid overheating.
Humidity and Hydration: Requires high humidity, consistently between 80% and 90%. Spraying the terrarium twice daily with RO water is essential. Provide a very shallow, clean water dish to prevent any drowning hazard.
Feeding and Supplementation: Feed exclusively on appropriately sized live prey: fruit flies (Drosophila melanogaster and hydei), pinhead crickets, springtails, and small isopods. Dust prey with calcium and vitamin D3 twice weekly.
Compatibility: Can be kept in small mixed-sex groups in large setups with plenty of visual barriers. Must not be housed with larger predators or other amphibian species to prevent stress and disease transmission.
Health and Common Diseases: Highly vulnerable to dehydration and bacterial or fungal skin infections (such as chytridiomycosis) resulting from poor sanitation or waterlogged substrate. Ensure adequate ventilation to prevent stagnant air.

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 frogs.
- 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.
