Species Profile
Species profile data sourced from the IUCN Red List of Threatened Species.
The smooth egg-guarding frog faces severe population declines due to habitat destruction from deforestation and agricultural expansion throughout its limited range. Climate change is altering precipitation patterns critical for breeding, while the deadly chytrid fungus continues to devastate amphibian populations across its habitat.
Key Facts
Habitat & Distribution
This species inhabits humid montane cloud forests and adjacent stream systems at elevations between 1,200-2,400 meters. It requires pristine forest streams with rocky substrates where males can guard their terrestrial egg clutches in moist crevices near water sources.
