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

Highly adaptable, inhabiting forest edges, grasslands, and urban gardens near water sources.

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

Nocturnal; spends days buried in soil or under debris, emerging at dusk.

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

Solitary except for mating aggregations at breeding sites.

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

Nocturnal ground-foraging insectivore.

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

Feeds primarily on a wide variety of arthropods, including ants, beetles, and crickets.

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

Explosive breeder in temporary or permanent water bodies after rainfall.

Males3 - 6 Years
Females3 - 6 Years

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

Males Multi-lang

Males are smaller and have a vocal sac to produce a high-pitched trill.

Females Multi-lang

Females are larger and lack the vocal sac used by males.

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

Distinct cranial crests aid in burrowing, and warty skin helps in moisture retention.

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

Habitat loss and vulnerability to road mortality and pesticide exposure.

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

It is one of the most common toads in its range, often seen under porch lights catching insects.
