PhylumRank below Kingdom. Groups organisms sharing a fundamental body plan (e.g., Chordata = vertebrates and some invertebrates).Chordata
ClassRank below Phylum. Subdivides by structural traits (e.g., Mammalia, Aves, Reptilia, Insecta).Amphibia
OrderRank below Class. Groups related families sharing common ancestry (e.g., Carnivora, Primates).Anura
FamilyRank below Order. Groups closely related genera (e.g., Felidae = cats, Canidae = dogs).Phyllomedusidae

Sexual DimorphismPhysical differences in size, coloration, or morphology between males and females of this species.
Males Multi-lang
Slightly smaller, with developed vocal sacs.
Females Multi-lang
Slightly larger and robust.
Evolutionary AdaptationsInherited traits and behaviors that improve the species' survival and reproduction in its specific environment. Multi-lang
Aposematic coloration on the flanks to deter predators when moving.
Main ThreatsDocumented pressures reducing the population: habitat loss, hunting, disease, climate change, and invasive species. Multi-lang
Habitat loss due to agricultural expansion and climate change affecting the availability of breeding sites.
Interesting FactsSurprising or notable facts that highlight what makes this species unique or ecologically important. Multi-lang
Like other members of Phyllomedusidae, it deposits eggs on leaves above water so tadpoles fall upon hatching.
