Description de l'espèce
Geographical Origin and Habitat: Native to New Guinea (Star Mountains, border region). It primarily occurs in subalpine forests at high elevations exposed to very cool temperatures. It lives mostly concealed within leaf litter or burrowed inside moist soils.
Taxonomy and Genetics: Belongs to the Microhylidae family, genus Choerophryne. This group consists of narrow-mouthed frogs highly adapted to specific fossorial or semi-arboreal microhabitats.
Behavior and Habits: Primarily nocturnal and secretive. It spends the daytime hours buried under the substrate or hidden beneath leaf litter, emerging to forage and breed during heavy seasonal rains.
Morphology: Features a plump, rounded body reaching about 1.6 cm. Skin texture ranges from smooth to warty with cryptic colors. Males are smaller than females and exhibit distinct vocal sacs during the breeding season.
Soins, reproduction et cohabitation
Terrarium Setup: Provide a horizontal terrarium with a deep (10-15 cm) layer of loose, damp substrate such as coconut fiber and sterile peat moss. Add cork bark hides, dry leaves, and flat shelters to create shaded spots.
Lighting and Heating: Maintain daytime temperatures around 18.0°C and night temperatures at 13.0°C. Provide a 12-hour light cycle; a low-intensity UVB source is recommended to support general health.
Humidity and Hydration: Maintain relative humidity between 80.0% and 95.0%. Mist regularly with dechlorinated water and supply a very shallow water dish to prevent drowning risks.
Feeding and Supplementation: Strictly insectivorous. Offer gutloaded crickets, roaches, fruit flies, and small worms. Dust prey with high-quality calcium and vitamin D3 twice a week to support skeletal structure.
Compatibility: Best kept in a species-specific setup. Small groups of similar size can cohabitate, avoiding competition or accidental cannibalism.
Health and Common Diseases: Highly susceptible to bacterial skin infections (red leg disease) if ventilation is poor or the substrate is soiled. Regularly check skin condition and hydration levels.

Profil d'amphibien
- Régime alimentaire
- Insectivore
- It feeds on microscopic invertebrates, such as collembolans, tiny beetles, and mites. It uses its dark, cryptic coloration to remain hidden while ambushing small prey on the forest floor. The frog's tiny jaws strongly restrict it to consuming only the smallest of insects.
- Espérance de vie
- 5-8 years
- Taille adulte
- 1.8 cm
- Mode de vie/microhabitat
- Terrestrial
- They are predominantly terrestrial, living on the forest floor and navigating through dense leaf litter and ground vegetation.
- Cycle d'activité
- Nocturnal
- This species is primarily nocturnal, remaining hidden during the day in leaf litter or burrows and emerging at night to forage for food.
- Sociabilité
- Solitary
- It is predominantly active at night, utilizing the dark and damp conditions of the forest floor. Males vocalize with a series of distinct clicks to establish territory. Its dark coloration helps it blend perfectly into the shadows and damp earth.
- Reproduction
- Oviparous
- It relies on direct development, laying eggs in sheltered, damp spots within the deep leaf litter. The entire embryonic development occurs within the egg capsule, bypassing the tadpole stage. The young hatch as miniature, fully formed terrestrial frogs.
- Toxicité
- Toxic
- This species is completely non-venomous and lacks any known toxic skin secretions. It avoids predation strictly through its exceptional camouflage and secretive habits. Predators often walk right past it.
- Stade de vie
- Adult only
- It never experiences an aquatic phase, hatching straight into a terrestrial juvenile. The frog remains highly reliant on the high humidity of its environment to maintain moisture. It stays small and terrestrial throughout its life.
- Tolérance aux manipulations
- Display only
- Due to their sensitive skin and potential stress from handling, they should be considered a display-only species.
- Brumation
- Non requise
- They do not require a brumation period, maintaining a steady metabolic rate year-round in their native tropical habitats.
- Mue
- Periodic
- Shedding occurs periodically and is facilitated by high environmental humidity; the shed skin is typically consumed immediately by the animal.
