Steyermark's Pancake Frog
Otophryne steyermarki
A specialized microhylid frog (4.5 cm) native to South America (Tepuis of Venezuela, including Mount Roraima). Characterized by its adaptation to cold montane temperatures and a dark, nearly black coloration and fossorial, leaf-litter dwelling habits.

Descrição da espécie
Geographical Origin and Habitat: Native to South America (Tepuis of Venezuela, including Mount Roraima). It primarily occurs on the foggy rocky summit plateaus of sandstone tepuis with constant cloud cover (1800-2600 m). It lives mostly concealed within leaf litter or burrowed inside moist soils.
Taxonomy and Genetics: Belongs to the Microhylidae family, genus Otophryne. 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 4.5 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 17.0°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.

Perfil anfíbio
- Dieta
- Insectivore
- Otophryne steyermarki 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
- 5-7 years
- Tamanho adulto
- 4.5 cm
- Estilo de vida/Microhabitat
- Terrestrial
- Otophryne steyermarki 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
- Diurnal
- The activity pattern of Otophryne steyermarki 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
- Otophryne steyermarki 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 Otophryne steyermarki 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
- Harmless
- Like its relatives, it lacks potent toxins but can exude a sticky, unpalatable mucus. This secretion helps to deter opportunistic predators such as spiders or small highland snakes. It is completely harmless to humans.
- Estágio de vida
- Metamorphosis
- The unusual tadpoles spend their time suspended near the water's surface, filtering food. Metamorphosis yields tiny froglets that immediately take on the distinctively flat appearance of the adults. The adult frogs remain small, inhabiting the dense, mossy undergrowth of the tepuis.
- Tolerância de tratamento
- Display only
- Should be considered a display-only species to protect its delicate, permeable skin from the oils and salts of human hands.
- Brumação
- Não obrigatório
- Native to tropical South America, they do not require any form of brumation and thrive in consistent year-round warm temperatures.
- Muda
- Periodic
- Requires a highly humid environment to shed its skin properly. The shedding process is quick and the old skin is generally ingested.
