Habitat SummaryOverview of the specific ecosystems and environments where this species is found in Costa Rica. Multi-lang
Inhabits humid tropical rainforests, swampy areas, and river edges. It is frequently found in low vegetation, shrubs, and floodable grasslands.BehaviourDaily activity patterns, movement, territory use, foraging style, and seasonal behavioral changes. Multi-lang
Nocturnal species highly active during rainy nights. It spends the day resting, well hidden among the leaves of epiphytic plants or in low vegetation.Social ActivitySocial structure: whether the species is solitary, paired, or colonial; hierarchy and communication. Multi-lang
Solitary, although during the breeding season males congregate in ponds and flooded areas to form choruses and compete for mates.Feeding GuildWhat the species eats, how it forages or hunts, and its role as a consumer in the food web. Multi-lang
Active ambush hunter. Uses binocular vision to detect the movement of small prey among the foliage and captures them with a quick strike of its sticky tongue.Trophic Chain DetailsSpecific interactions in local food webs: prey species, predators, competitors, and scavengers. Multi-lang
Insectivore. Feeds mainly on small flying insects, ants, mites, and spiders that it actively hunts in the low arboreal vegetation.Reproductive BehaviourMating strategies, courtship displays, nesting or spawning behavior, and parental care. Multi-lang
Oviparous species. The female lays its eggs in water or on submerged vegetation of temporary ponds, where the tadpoles complete their development.Physical Measures

Sexual DimorphismPhysical differences in size, coloration, or morphology between males and females of this species.
Males Multi-lang
Males are generally smaller and possess more prominent vocal sacs that inflate considerably during the emission of their mating songs.
Females Multi-lang
Females have a larger and more robust body structure, necessary to house a larger number of eggs before the breeding season.
Evolutionary AdaptationsInherited traits and behaviors that improve the species' survival and reproduction in its specific environment. Multi-lang
Chromatic camouflage: Its skin can darken or lighten depending on ambient light and the surface it rests upon, optimizing its invisibility to potential predators.
Main ThreatsDocumented pressures reducing the population: habitat loss, hunting, disease, climate change, and invasive species. Multi-lang
Habitat degradation and desiccation of temporary ponds. The loss of clean water bodies directly affects its reproductive success.
Interesting FactsSurprising or notable facts that highlight what makes this species unique or ecologically important. Multi-lang
Distinctive vocalizations: Males emit a series of clicks or repetitive notes that resemble small metallic sounds, essential for attracting females in dense vegetation.
