Descrição da espécie
Geographical Origin and Habitat: Cornufer neckeri is endemic to the Solomon Islands archipelago, distributed across islands including Bougainville, Choiseul, Santa Isabel, and Guadalcanal. It inhabits wet tropical rainforests, showing a strong preference for riparian zones, rocky streams, and damp ravines. It is frequently found on wet rocks or low-hanging vegetation near fast-flowing water.
Taxonomy and Genetics: Belonging to the family Ceratobatrachidae, genus Cornufer, this species exhibits direct development. Eggs are deposited in damp terrestrial sites and hatch directly into miniature froglets. Genetic studies show subtle morphological and call variations between isolated island populations, reflecting geographic speciation.
Behavior and Habits: Primarily nocturnal and semi-aquatic or stream-dwelling. It is an agile jumper, using its powerful hind limbs to leap into the water or hide in rock crevices when threatened. During the day, it retreats into damp caves, under wet stones, or inside rock fissures near waterfalls. Males call at night from wet rocks.
Morphology: Features a more slender and stream-lined body compared to its terrestrial congeners. It possesses long hind legs and expanded toe discs that help it grip wet, slippery rock surfaces. The coloration is highly variable, ranging from olive-brown to greyish tones with dark bandings on the limbs and dorsal mottling.
Cuidado, criação e companheiros de tanque
Terrarium Setup: A paludarium or a tall humid terrarium with a substantial water section is recommended, with minimum dimensions of 60x45x60 cm. The land portion should feature drainage layers, organic soil, river stones, and moss. Furnish with water-resistant driftwood, slate rocks, and moisture-loving plants like ferns and mosses.
Lighting and Heating: Prefers moderate conditions: day temperatures of 22°C to 25°C and night temperatures of 18°C to 20°C. Avoid temperatures above 26°C. If heating is required, an aquarium heater with a protective guard can be placed in the water section. Use low-output LED lighting on a 12-hour timer.
Humidity and Hydration: Maintain high humidity levels between 80% and 95%. A small waterfall or water pump creates water movement that simulates their natural stream environment and keeps humidity high. Mist the terrarium daily with dechlorinated or reverse osmosis water.
Feeding and Supplementation: Strictly insectivorous. Offer active live prey such as crickets, flies, small roaches, and earthworms. Feeder insects must be gut-loaded and dusted with calcium and multivitamin powders containing vitamin A once a week to support metabolic processes and skin health.
Compatibility: Territorial, especially adult males near water sources. Keep them individually or as a confirmed pair in a spacious setup. Do not house with other species, as the semi-aquatic nature of this frog makes it sensitive to overcrowding and competition for prime basking spots.
Health and Common Diseases: Water quality in the aquatic section is critical. Ammonia or chlorine exposure can lead to rapid toxicity and skin sloughing. Prone to bacterial infections (red leg) and fungal diseases if water filtration is inadequate. Change water regularly and clean the mechanical filter media.

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.
