Habitat SummaryOverview of the specific ecosystems and environments where this species is found in Costa Rica. Multi-lang
Cloud forests and humid lowland areas in Costa Rica and Panama, preferring arboreal strata near streams.BehaviourDaily activity patterns, movement, territory use, foraging style, and seasonal behavioral changes. Multi-lang
Nocturnal; during the day it rests under leaves where its bright green color blends in perfectly.Social ActivitySocial structure: whether the species is solitary, paired, or colonial; hierarchy and communication. Multi-lang
Solitary, but congregates at specific sites near streams to breed.Feeding GuildWhat the species eats, how it forages or hunts, and its role as a consumer in the food web. Multi-lang
Hunts by ambushing prey passing near its resting position.Trophic Chain DetailsSpecific interactions in local food webs: prey species, predators, competitors, and scavengers. Multi-lang
Insectivorous, consumes small arthropods found in the canopy.Reproductive BehaviourMating strategies, courtship displays, nesting or spawning behavior, and parental care. Multi-lang

Sexual DimorphismPhysical differences in size, coloration, or morphology between males and females of this species.
Males Multi-lang
Generally smaller and with a slimmer body structure.
Females Multi-lang
Larger and robust, necessary for egg production.
Evolutionary AdaptationsInherited traits and behaviors that improve the species' survival and reproduction in its specific environment. Multi-lang
Chromatic change ability (metachrosis) that helps it thermoregulate and camouflage effectively.
Main ThreatsDocumented pressures reducing the population: habitat loss, hunting, disease, climate change, and invasive species. Multi-lang
Mainly affected by the chytrid fungus (Batrachochytrium dendrobatidis) and destruction of its forest habitat.
Interesting FactsSurprising or notable facts that highlight what makes this species unique or ecologically important. Multi-lang
It is one of the species that almost completely disappeared due to chytridiomycosis, but successful captive breeding programs have been achieved.
