The glass frogs are frogs of the amphibian family Centrolenidae. While the general background coloration of most glass frogs is primarily lime green, the abdominal skin of some members of this family is transparent and translucent. The internal viscera, including the heart, liver, and gastrointestinal tract, are visible through the skin, hence the common name is given as glass frog. Glass frogs are arboreal, meaning they mainly live in trees, and only come out for mating season.
Cochranella is a genus of glass frogs, family Centrolenidae. They are found in Central America from Honduras southward to the Amazonian and Andean cloud forests of Colombia, Ecuador, Peru, and Bolivia.
Nymphargus armatus is a species of frog in the family Centrolenidae. It is endemic to Colombia and only known from the immediate vicinity of its type locality in El Cairo municipality, Valle del Cauca Department. In much of the literature it is known as Cochranella armata as it was moved to its present genus only in 2007.
Nymphargus balionota is a species of frog in the family Centrolenidae. It is found in the Andes of Colombia and Ecuador. Common names Mindo Cochran frog and mottled glassfrog has been coined for it.
Nymphargus chami is a species of frog in the family Centrolenidae, formerly placed in Cochranella. It is endemic to Colombia where it occurs on the Cordillera Occidental in the Antioquia and Risaralda departments. Its natural habitats are very humid tropical forests and cloud forests where it occurs on vegetation next to streams. Its conservation status is unclear but threats to it include timber extraction, cattle raising and agricultural development.
Nymphargus cristinae is a species of frog in the family Centrolenidae, formerly placed in Cochranella. It is endemic to Colombia where it is only known near its type locality on the western slope of the Cordillera Occidental in Urrao, Antioquia. Its natural habitat is sub-Andean primary forest. It occurs on vegetation next to streams with canopy cover over the stream. Its conservation status is unclear but habitat degradation and loss caused by cattle raising, timber extraction, and cultivation of illegal crops are major threats.
Cochranella euknemos, sometimes known as the San Jose Cochran frog, is a species of frog in the family Centrolenidae. It is found in central Costa Rica and south/eastward to Panama and to the western flank of the Cordillera Occidental in Colombia. Some Colombian records might apply to Cochranella mache.
Nymphargus garciae is a species of frog in the family Centrolenidae, formerly placed in Cochranella. It is endemic to the eastern slopes of the Cordillera Central, Colombia. Its natural habitat is vegetation alongside streams in sub-Andean and Andean forests. It requires gallery forest for reproduction, and is therefore very sensitive to disturbance of this kind of habitat. It is threatened by habitat loss.
Cochranella mache, also known as the Mache glassfrog or Mache Cochran frog, is a species of frogs in the family Centrolenidae. It is found in the lowland forest and eastern slopes of Cordillera Mache–Chindul in the Esmeraldas Province, northwestern Ecuador, and in the western foothills of the Cordillera Occidental in Colombia.
Nymphargus nephelophila is a species of frogs in the family Centrolenidae, formerly placed in Cochranella. It is endemic to the Caquetá Department, Colombia, where it is known from the eastern versant of the Cordillera Oriental near Florencia. Its natural habitat is vegetation near streams in cloud forest, including secondary forest. Habitat loss is a threat to this species, but it is too little known to assess its conservation status.
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.
Nymphargus oreonympha is a species of frog in the family Centrolenidae, formerly placed in Cochranella. It is endemic to Colombia where it occurs on the Cordillera Oriental in Florencia, the Caquetá Department. Its natural habitat is cloud forest, including secondary forest, where it occurs on vegetation near streams. Its conservation status is unclear.
Nymphargus posadae is a species of frog in the family Centrolenidae, formerly placed in Cochranella. It inhabits the eastern slopes of the Andes of Colombia, Ecuador, and northeastern Peru. It is reasonably common in Colombia but rare in Ecuador.
Cochranella resplendens is a species of frog in the family Centrolenidae. It is found in the upper Amazon Basin in southern Colombia, eastern Ecuador, and San Martín Region of northern Peru. It is sometimes known as the resplendent Cochran frog.
"Cochranella" riveroi is a species of frog in the family Centrolenidae. It is endemic to Cerro Aracamuni, Venezuela. The generic placement of this species within the subfamily Centroleninae is uncertain.
Rulyrana saxiscandens is a species of frog in the family Centrolenidae. It is endemic to the Cordillera Escalera, Peru, approximately between the cities of Tarapoto and Moyobamba.
Nymphargus siren is a species of frog in the family Centrolenidae, formerly placed in Cochranella. It is found in Colombia, Ecuador, and Peru. Its natural habitats are pre-montane forests near streams. It is threatened by habitat loss.
Nymphargus spilotus is a species of frog in the family Centrolenidae, formerly placed in Cochranella. It is endemic to Colombia where it occurs on the Cordillera Central in Samaná, the Caldas Department. Its natural habitat is sub-Andean forest where it occurs on vegetation alongside streams. Its conservation status is unclear.
Cochranella vozmedianoi is a species of frog in the family Centrolenidae, endemic to the Cerro El Humo, in the Paria Peninsula in northern Venezuela.
The powdered glass frog or Chiriqui glass frog, Teratohyla pulverata, is a frog species in the glass frog family (Centrolenidae). It is found from north-central Honduras south to northwestern Ecuador.
