Descrição da espécie
Geographical Origin and Habitat: Native to Central China (Sichuan, Gansu, Shaanxi). It primarily occurs in temperate hill forests, cultivated fields, and damp rocky gardens. It lives mostly concealed within leaf litter or burrowed inside moist soils.
Taxonomy and Genetics: Belongs to the Microhylidae family, genus Kaloula. 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 4.8 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.
Cuidado, criação e companheiros de tanque
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 22.0°C and night temperatures at 17.0°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 65.0% and 80.0%. 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.

- Dieta
- Insectivore
- Kaloula rugifera has a specialized diet consisting primarily of small insects and invertebrates found in its natural habitat. It actively hunts for prey during its peak activity hours, utilizing its agile movements to capture food. Nutritional supplementation is often required in captivity to maintain its health and vitality. Caretakers should ensure a varied diet to prevent nutritional deficiencies and promote natural feeding behaviors.
- Expectativa de vida
- 6-8 years
- Tamanho adulto
- 5.5 cm
- Estilo de vida/Microhabitat
- Fossorial
- Kaloula rugifera leads a specialized lifestyle adapted to the unique challenges of its native ecosystem. Its daily routine revolves around securing adequate nutrition, avoiding natural predators, and maintaining optimal body temperature. The species has evolved specific morphological traits that aid in its distinct way of living, whether arboreal, terrestrial, or aquatic. Understanding its lifestyle is fundamental to providing a suitable and enriching captive environment.
- Ciclo de atividades
- Nocturnal
- The activity pattern of Kaloula rugifera is distinctly regulated by its circadian rhythm and the ambient temperature of its environment. It may exhibit nocturnal, diurnal, or crepuscular habits depending on its specific evolutionary adaptations. These patterns are essential for thermoregulation, predator avoidance, and efficient foraging within its habitat. Caretakers should carefully provide appropriate lighting and heating cycles to match these natural rhythms.
- Socialidade
- Solitary
- Kaloula rugifera exhibits a fascinating array of behaviors that are closely tied to its ecological niche and survival strategies. It is known to display territorial behaviors, especially during the breeding season or when competing for limited resources. Social interactions can vary significantly, ranging from solitary habits to complex group dynamics depending on the context. Observing these behaviors provides valuable insights into its overall well-being and environmental suitability.
- Reprodução
- Oviparous
- The reproductive cycle of Kaloula rugifera is highly dependent on environmental cues such as temperature and humidity changes. Mating typically occurs during specific seasons when environmental conditions are optimal for the survival of offspring. Courtship behaviors are distinct and play a crucial role in successful mating and fertilization. Breeders must replicate these natural conditions carefully to encourage reproduction in a captive setting.
- Toxicidade
- Mildly toxic
- They are completely non-toxic and rely on their plump shape and burrowing habits for defense. When threatened, they can inflate their bodies significantly to appear larger. They pose no risk of toxic secretions to humans or other pets.
- Estágio de vida
- Metamorphosis
- Like most Kaloula species, they lay eggs in temporary pools formed by heavy rains. The tadpoles hatch and undergo a rapid metamorphosis to escape the drying pools. The terrestrial froglets grow quickly, reaching sexual maturity within their first year.
- Tolerância de tratamento
- Display only
- Handling should be kept to an absolute minimum to avoid stressing the animal. Their skin easily absorbs harmful oils and residues from human hands. If relocation is required, carefully scooping them into a plastic container is the safest method.
- Brumação
- Não obrigatório
- Native to Sichuan, China, they naturally experience cooler winters and will enter brumation. They burrow deep into the substrate and remain dormant until temperatures rise in spring. In captivity, a controlled cooling period can be offered to simulate this natural cycle.
- Muda
- Periodic
- Regular molting is crucial for maintaining a healthy, moisture-permeable epidermal layer. The process is quick and involves the frog contorting to pull the old skin into its mouth. The consumed shed provides a valuable source of recycled nutrients.
