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

Inhabits lowland tropical humid forests near ponds and slow-moving rivers.

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

Nocturnal and arboreal; during the day it hides under leaves, concealing its bright colors.

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

Solitary except during the breeding season, when they congregate near water.

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

Carnivore. Feeds mainly on crickets, moths, flies, and other nocturnal insects.

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

Insect population controller and prey for birds, bats, and arboreal snakes.

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

Lays eggs in gelatinous masses on leaves overhanging water; tadpoles fall into the water upon hatching.

Gestation / IncubationDuration from fertilization to birth (mammals) or to hatching (egg-laying species).

6 - 10

Lifespan EstimatedExpected duration of life from birth to natural death under wild conditions.
Males3 - 5 Years
Females3 - 5 Years

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

Males Multi-lang

Males are smaller and emit mating calls to attract females.

Females Multi-lang

Females are notably larger and more robust than males.

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

Its large red eyes serve to momentarily startle predators (startle coloration),
Adhesive discs on toes for climbing smooth, wet surfaces.

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

Water pollution and habitat loss due to deforestation.

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

Embryos can detect vibrations from predators and hatch prematurely to escape.
