[[7][2][3] The decline in amphibian populations is well documented. The Atelopus balios is Critically Endangered as a result of the widespread amphibian Chytridiomycosis fungus that has decimated other amphibian populations.[4]]Description
Adult males measure {{convert|27|-|29|mm|abbr=on}}[ and females {{convert|35|-|37|mm|abbr=on}} in snout–vent length.[12] The snout is The limbs are long and slender. The fingers and toes are partially webbed.[2] The dorsum is olive green and is covered with rounded black spots that also extend to the limbs. The palms, soles, webbing, and perianal region are orange. The belly is almost totally cream yellow, except for the margins to which the black spots extend.[12]]
Habitat and conservation
Its natural habitats are tropical lowland rainforests at elevations of {{convert|200|–|460|m|abbr=on}}[1] or {{convert|0|–|900|m|abbr=on}}[ above sea level, depending on the source. It is nocturnal and associated with streams.][ It is threatened by chytridiomycosis and habitat loss caused by agriculture, logging, and pollution. Its range does not include any protected areas.[1]]
