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

Inhabits a wide variety of environments, from humid jungles to urban areas, gardens, and agricultural zones. It is a species highly tolerant of human disturbance.

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

Nocturnal and active species. Congregates massively in puddles and temporary ponds after rain to start its reproductive choruses.

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

Social during the breeding season, forming choruses where males actively compete for the attention of females.

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

Active ground hunter. Searches for prey in leaf litter and captures them quickly with its sticky tongue.

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

Opportunistic insectivore. Its diet consists mainly of ants, beetles, spiders, and other small soil invertebrates.

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

Oviparous with foam nests. Eggs are deposited in a foam nest that floats in the water until the tadpoles hatch.

Lifespan EstimatedExpected duration of life from birth to natural death under wild conditions.
Males2 - 4 Years
Females2 - 4 Years

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

Males Multi-lang

Males are somewhat smaller and possess highly distensible vocal sacs to produce their complex calls.

Females Multi-lang

Females are larger and more robust, allowing for a greater capacity for egg-laying in the foam nest.

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

Behavioral adaptability: Males can adjust the complexity of their call based on the presence of competitors or predators (like bats).

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

Although resilient, contamination of temporary ponds and alteration of rain cycles can reduce its reproductive success.

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

Foam nest: The female beats the eggs with her hind legs along with glandular secretions to create a floating foam nest that protects the clutch.
