Habitat SummaryOverview of the specific ecosystems and environments where this species is found in Costa Rica. Multi-lang
Species associated with streams and fast-flowing brooks in premontane and cloud forests of Costa Rica and Panama.BehaviourDaily activity patterns, movement, territory use, foraging style, and seasonal behavioral changes. Multi-lang
Mainly nocturnal and dependent on vegetation bordering streams.Social ActivitySocial structure: whether the species is solitary, paired, or colonial; hierarchy and communication. Multi-lang

Main ThreatsDocumented pressures reducing the population: habitat loss, hunting, disease, climate change, and invasive species. Multi-lang
Very vulnerable to chytridiomycosis and the degradation of riparian ecosystems due to human activities.
Interesting FactsSurprising or notable facts that highlight what makes this species unique or ecologically important. Multi-lang
Unlike many other frogs, this species deposits its eggs on rocks or vegetation just above the water level of streams.
