Torricelli Mountain Frog
Choerophryne rostellifer
A specialized microhylid frog (1.8 cm) native to New Guinea (Torricelli Mountains, Papua New Guinea). Characterized by its tiny fleshy projection on its snout that acts as camouflage and fossorial, leaf-litter dwelling habits.

Description de l'espèce
Geographical Origin and Habitat: Native to New Guinea (Torricelli Mountains, Papua New Guinea). It primarily occurs in montane cloud forests of the Torricelli range, living in low herbaceous plants and leaf litter. 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
- This tiny amphibian forages for invertebrates such as collembolans, mites, and small spiders. Its extremely small mouth limits it to hunting micro-prey scattered across the forest floor. It is an active hunter that constantly probes the damp moss for a meal.
- Espérance de vie
- 3-5 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
- An elusive species, it dwells among the roots and leaf litter of high-elevation rainforests. Males emit a series of rapid clicking sounds to establish territory and attract mates. The species is highly sensitive to changes in humidity and temperature.
- Reproduction
- Oviparous
- It reproduces via direct development, laying small clutches of robust eggs in damp, hidden locations. There is no aquatic tadpole stage; instead, embryonic development occurs entirely within the egg capsule. Miniature frogs hatch directly onto the moist forest floor.
- Toxicité
- Harmless
- It lacks any known toxins or chemical deterrents against predators. Instead, its tiny size and mottled brown coloration provide excellent camouflage. This physical concealment is its sole defense mechanism.
- Stade de vie
- Adult only
- The species hatches as a precise miniature of the adult, fully adapted to life on land from day one. It never experiences a gill-breathing, aquatic phase. It remains deeply tied to the humid microclimates of the forest as it grows.
- 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.
