Atelopus coynei, the Rio Faisanes stubfoot toad, is a species of toad in the family Bufonidae endemic to Ecuador. Its natural habitats are subtropical or tropical moist lowland forests, subtropical or tropical moist montane forests, and rivers. It is threatened by habitat loss. [1]
Atelopus coynei can be differentiated from other similar species by its ventral patterning, thick fleshy finger webbing that covers its first finger, and from its long hind limbs that cause its heels to overlap when the legs are positioned perpendicular to the body (Miyata 1980). [2]
Atelopus coynei formerly ranged across the northwestern Andes foothills in Carchi, Imbabura, Pichincha and Santo Domingo provinces of Ecuador, where it lives along stream banks in primary and secondary montane forest between 500 and 2,000 meters elevation. [1]
It currently found in only four disjunct areas in Carchi Province, including two locations in Dracula Reserve and Río Chinambi. [1]
Adults are diurnal, active on rainy days on the rocky banks of river and streams. They rest at night on the leaves of streamside vegetation. They lay eggs on rocks in flowing streams. Tadpoles are typical of Atelopus , remaining attached to rocks. [1]
The conservation status of Atelopus coynei is assessed as critically endangered. It has a very small population which is continually declining from loss and degradation of its habitat, chiefly from agricultural activities. The population is estimated at fewer than 250 mature individuals. [1]
It was named after evolutionary biologist Jerry Coyne, who collected the holotype in a swamp on a frogging trip to western Ecuador as a student in the late 1970s. [3] It was thought to be extinct for many years, but was observed and photographed on February 7, 2012, by photographer Andreas Kay. [4]
The ancestral stock of the genus Atelopus was thought to be present in South America prior to the Tertiary era. [5] Species within the genus likely adapted to riparian habitats prior to the Andean uplift in the Cretaceous and Early Tertiary. As Andean uplift occurred, creating a more montane environment, it lifted the species and speciation resulted for the medium- to higher-altitude species members including A. coynei; this higher-altitude adaptation likely reflected the ensuing vegetation and climate.
Atelopus angelito, the Angelito stubfoot toad, is a species of toads in the family Bufonidae endemic to Colombia. Its natural habitats are subtropical or tropical moist montane forests, subtropical or tropical high-altitude shrubland, and rivers.
Atelopus arthuri, Arthur's stubfoot toad, is a species of toad in the family Bufonidae endemic to Ecuador.

The Guajira stubfoot toad or Carrikeri harlequin frog is a species of toad in the family Bufonidae. It is about 5 cm (2.0 in) long and typically black, though some populations have orange coloration. This species is endemic to the Sierra Nevada de Santa Marta mountain range of northern Colombia. It is critically endangered because of the chytrid fungus, Batrachochytrium dendrobatidis, and habitat destruction due to agriculture. The species had not been seen from 1994 until it was rediscovered in early 2008.

Atelopus lynchi is a species of toad in the family Bufonidae. It is endemic to Ecuador. Its natural habitats are subtropical or tropical moist lowland forests, subtropical or tropical moist montane forests, and rivers. It is threatened by habitat loss.
Atelopus mandingues is a species of toads in the family Bufonidae.
Atelopus muisca is an extinct species of toad in the family Bufonidae. It is endemic to Colombia. Its natural habitats were subtropical or tropical moist montane forests, subtropical or tropical high-altitude grassland, and rivers. It is threatened by habitat loss.
Atelopus petriruizi, more commonly known as the painted stubfoof toad, is a species of toad in the family Bufonidae. Endemic to Colombia, the toad's natural habitats are subtropical or tropical moist montane forests and rivers. Threatened by habitat loss, the Ateopus petriruizi is currently classified as critically endangered, and was placed on the IUCN red list in 2017. Currently, there may be less than 49 remaining mature A. Petriruizi.

Its natural habitats are subtropical or tropical dry forest, subtropical or tropical moist lowland forest, subtropical or tropical moist montane forest, dry savanna, moist savanna, temperate shrubland, subtropical or tropical dry shrubland, subtropical or tropical moist shrubland, subtropical or tropical dry lowland grassland, subtropical or tropical seasonally wet or flooded lowland grassland, subtropical or tropical high-altitude grassland, intermittent rivers, freshwater lakes, intermittent freshwater lakes, freshwater marshes, intermittent freshwater marshes, arable land, pastureland, rural gardens, urban areas, heavily degraded former forest, ponds, and canals and ditches.
"Centrolene" petrophilum is a species of frog in the family Centrolenidae. Also called the Boyaca Giant Glass Frog.
Cochranella nola is a species of frog in the family Centrolenidae, the glass frogs, so named because of the transparent skin on the underside of the abdomen through which the internal organs can be seen. This species is endemic to Bolivia where it is found in the Andean foothills in the Santa Cruz Department. Its natural habitats are subtropical or tropical moist montane forests and rivers. The scientific name nola is Latin for "small bell", and refers to the high-pitched, bell-like call of the male in the breeding season.

The Northwestern Andean montane forests (NT0145) is an ecoregion on the Andes mountains in the west of Colombia and Ecuador. Both flora and fauna are highly diverse due to effect of ice ages when the warmer climate zones were separated and the cooler ones combined, and interglacial periods when the reverse occurred. Because the environment is hospitable to humans, the habitat has been drastically modified by farming and grazing since the Pre-Columbian era.
The Eastern Cordillera Real montane forests (NT0121) is an ecoregion in the eastern range of the Andes of southern Colombia, Ecuador and northern Peru. The ecoregion covers the eastern slopes of the Andes, and includes montane forest that rises from the Amazonian rain forest, with cloud forest and elfin forest at higher elevations. It is rich in species, including many endemics. It is threatened by logging and conversion for pasturage and subsistence agriculture.
