Description de l'espèce
Geographical Origin and Habitat: Native to New Guinea (Bewani Mountains, Menawa area). It primarily occurs in mossy dry beds of mountain torrents within submontane rainforests. 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 1.8 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 20.0°C and night temperatures at 16.0°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 specializes in a diet of tiny arthropods, primarily targeting mites and very small ants. Due to its elongated snout and tiny mouth, it is restricted to consuming micro-invertebrates. It actively searches the leaf litter using its keen vision to spot minute movement.
- Espérance de vie
- 2-5 years
- Taille adulte
- 1.5 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
- This is a cryptic, ground-dwelling frog that prefers the dense, humid understory of the rainforest. Males emit sharp, insect-like chirps at night to attract females and ward off rivals. When disturbed, it remains completely motionless to avoid detection.
- Reproduction
- Oviparous
- Like other members of its genus, it reproduces through direct development. A small clutch of eggs is hidden in a moist, terrestrial location where they incubate. The offspring hatch as tiny froglets, successfully skipping the aquatic larval stage.
- Toxicité
- Toxic
- This species is not toxic and lacks chemical defenses of any kind. Its survival depends entirely on its small size and effective camouflage. This makes it incredibly difficult for visual predators to spot in the dark forest.
- Stade de vie
- Adult only
- It emerges from the egg fully formed and terrestrial. It grows slowly, maintaining a diminutive size throughout its adult life. It never requires standing water to complete its life cycle.
- 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.
