The glass frogs belong to 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, giving the glass frog its common name. The internal viscera, including the heart, liver, and gastrointestinal tract, are visible through the skin. When active their blood makes them visible; when sleeping most of the blood is concealed in the liver, hiding them. Glass frogs are arboreal, living mainly in trees, and only come out for mating season. Their transparency conceals them very effectively when sleeping on a green leaf, as they habitually do.
Centrolene is a genus of glass frogs in the family Centrolenidae. The adult males are characterized by having a humeral spine, as most members of this family. The delimitation of this genus versus Cochranella is not fully resolved, and some species formerly in Centrolenella — which is nowadays synonymized with Centrolene — are now in Hyalinobatrachium.
Colostethus is a genus of poison dart frogs native to Central and South America, from Panama south to Colombia, Ecuador, and northern Peru. Their common name is rocket frogs, but this name may refer to frogs in other genera and families, following the taxonomic revision of the genus in 2006.
Hyloscirtus is a genus of Neotropical frogs in the family Hylidae. This genus was resurrected in 2005 following a major revision of the Hylidae, with the distinguishing features being 56 transformations in nuclear and mitochondrial proteins and ribosomal genes. Of these species, 28 species, previously placed in the genus Hyla, were moved to this genus. The fingers and toes of these frogs have wide dermal fringes.
Allobates is a genus of frogs in the family Aromobatidae. They are native to the Central and South Americas, from Nicaragua to Bolivia and Brazil, with one species on Martinique.
Aromobates, sometimes known as the skunk frogs, is a genus of frogs from the Andes of Venezuela and Colombia. Originally a monotypic genus consisting of the skunk frog, Aromobates nocturnus alone, it was later expanded to include Nephelobates. These frogs are difficult to differentiate from Allobates without using molecular markers.
Atelopus longirostris is a species of harlequin frog, a member of the family of true toads (Bufonidae). It has been recorded only in northern Ecuador. Records from Colombia probably represent different species. As of mid-2017, it is listed as extinct by the IUCN, but was rediscovered in 2016 after more than two decade with no sightings, likely because the IUCN last assessed it in 2004. The scientific name of this species means "long-snout" and the species has been named in Spanish as the jambato hocicudo. Common names longnose stubfoot toad, scrawny stubfoot-toad, and longnose sharlequin frog have been coined for it.
Atelopus carbonerensis, also known as the Venezuelan yellow frog and La Carbonera stubfoot toad, is a species of toad in the family Bufonidae. It is endemic to the Mérida Andes of Venezuela. Following an observation in 1998, it was feared extinct for nearly two decades until a single individual was sighted in 2014, followed by an observation of a mating pair in 2021.
Atelopus famelicus is a species of toad in the family Bufonidae endemic to Colombia. It is known from the Cordillera Occidental in Cauca and Valle del Cauca departments.
Silverstoneia erasmios is a species of frog in the family Dendrobatidae. It is endemic to Colombia where it is known from the Cordillera Occidental and Cordillera Central in the Antioquia Department.
Nymphargus is a genus of glass frogs in the subfamily Centroleninae, which was established in 2007. They are distributed in the Andean slopes of Colombia, Ecuador, Peru, and Bolivia. They are characterized by lacking webbing among the outer fingers, lacking humeral spines in adult males, and having a lobed liver covered by a transparent hepatic peritoneum. They can be more specifically characterized as having a head that is darker green than the body, there being yellow spots surrounded by black on head and body, upper eyelids are dark lavender. The conservation status of the Nymphargus frogs was largely believed to be critically endangered due to the minimal research done on this genus. Once the scope of the research was broadened the conservation status was able to be determined as being vulnerable. More frogs of different variations were found increasing the genus’ population.
Hyloxalus is a genus of poison dart frogs, family Dendrobatidae. The genus is distributed in Central and South America, from Panama south to Peru, along with Venezuela, Colombia, and Ecuador. They also inhabit the eastern foothills of the Andes in Bolivia to Venezuela, east to the upper Amazon Basin.
Ameerega is a genus of poison dart frogs in the family Dendrobatidae. These frogs live around rocks that are nearby streams. They are found in central South America north to Panama. It contains many former species of the genus Epipedobates.
Silverstoneia is a genus of poison dart frogs from southern Central America and northern South America, between southwestern Costa Rica and southwestern Colombia. It is named in honour of Phillip A. Silverstone, an expert on dendrobatoid frogs.
Sachatamia is a small genus of glass frogs. They are found in Central America and northern South America at altitudes below 1,500 m (4,900 ft) above sea level.
Ikakogi is a genus of frogs in the family Centrolenidae. It has been tentatively placed in the subfamily Centroleninae, although more recent analyses suggest that it is the sister group of the clade Centroleninae+Hyalinobatrachiinae.
Ectopoglossus is a genus of frogs in the subfamily Hyloxalinae, of the family Dendrobatidae.
Paruwrobates is a genus of frogs in the family Dendrobatidae. The frogs are found in the Pacific slopes of the Andes in southern Colombia and northern Ecuador.
Ikakogi ispacue is a species of amphibian in the Centrolenidae family, which can only be found in the northern Sierra Nevada de Santa Marta, in the department of Guajira, Colombia. It inhabits subtropical forests and is usually seen over vegetation and near streams.
