Habitat SummaryOverview of the specific ecosystems and environments where this species is found in Costa Rica. Multi-lang

Found in a wide range of humid lowlands, from open areas and grasslands to swampy vegetation and forest edges.

BehaviourDaily activity patterns, movement, territory use, foraging style, and seasonal behavioral changes. Multi-lang

Nocturnal species usually active in the lower part of the vegetation.

Social ActivitySocial structure: whether the species is solitary, paired, or colonial; hierarchy and communication. Multi-lang

Forms large reproductive choruses in ponds and pools during the rainy season.

Feeding GuildWhat the species eats, how it forages or hunts, and its role as a consumer in the food web. Multi-lang

Active hunter, detects its prey through movement and visual contact.

Trophic Chain DetailsSpecific interactions in local food webs: prey species, predators, competitors, and scavengers. Multi-lang

Feeds on small insects and arthropods that inhabit between the leaves.

Reproductive BehaviourMating strategies, courtship displays, nesting or spawning behavior, and parental care. Multi-lang

Explosive breeding in shallow water bodies.

Sexual DimorphismPhysical differences in size, coloration, or morphology between males and females of this species.

Males Multi-lang

Highly distensible vocal sacs to amplify its high-pitched call.

Females Multi-lang

Larger size than the male, with a more robust build.

Evolutionary AdaptationsInherited traits and behaviors that improve the species' survival and reproduction in its specific environment. Multi-lang

Minuscule size that allows it to hide effectively at the bases of leaves and in dense vegetation.

Main ThreatsDocumented pressures reducing the population: habitat loss, hunting, disease, climate change, and invasive species. Multi-lang

Sensitive to the loss of temporary wetlands and the use of agrochemicals in the grasslands where it inhabits.

Interesting FactsSurprising or notable facts that highlight what makes this species unique or ecologically important. Multi-lang

Despite its tiny size, males have an extremely high-pitched and persistent call that can be heard from great distances on rainy nights.
