Habitat SummaryOverview of the specific ecosystems and environments where this species is found in Costa Rica. Multi-lang
Inhabits humid lowland and montane forests, often found near streams or in areas with thick leaf litter where it can hide.BehaviourDaily activity patterns, movement, territory use, foraging style, and seasonal behavioral changes. Multi-lang
Nocturnal and terrestrial, spending most of its time hidden within leaf litter, where it hunts small insects.Social ActivitySocial structure: whether the species is solitary, paired, or colonial; hierarchy and communication. Multi-lang
Generally solitary, except during breeding events where males congregate to call.Feeding GuildWhat the species eats, how it forages or hunts, and its role as a consumer in the food web. Multi-lang
Terrestrial insectivore.Trophic Chain DetailsSpecific interactions in local food webs: prey species, predators, competitors, and scavengers. Multi-lang
Feeds on ants, mites, and other small arthropods. Preyed upon by larger frogs, snakes, and small mammals.Reproductive BehaviourMating strategies, courtship displays, nesting or spawning behavior, and parental care. Multi-lang
Males call from low vegetation or the ground. Eggs are laid in moist terrestrial sites.Physical Measures

Sexual DimorphismPhysical differences in size, coloration, or morphology between males and females of this species.
Males Multi-lang
Males are smaller and possess vocal slits.
Females Multi-lang
Females are larger, especially when gravid, with a more robust body shape.
Evolutionary AdaptationsInherited traits and behaviors that improve the species' survival and reproduction in its specific environment. Multi-lang
Direct development: They bypass the tadpole stage, with eggs hatching directly into fully formed froglets.
Main ThreatsDocumented pressures reducing the population: habitat loss, hunting, disease, climate change, and invasive species. Multi-lang
Habitat loss due to agricultural expansion and deforestation, and sensitivity to climate change.
Interesting FactsSurprising or notable facts that highlight what makes this species unique or ecologically important. Multi-lang
They are known for their distinct vocalizations, which are often heard during the wet season.
