The glass frogs belong to the amphibian family Centrolenidae, native to the Central American Rainforests. 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, feeding on small insects and only coming out for mating season. Their transparency conceals them very effectively when sleeping on a green leaf, as they habitually do. However, climate change and habitat fragmentation has been threatening the survival rates of the family.

The generic placement of this species within the subfamily Centroleninae is uncertain. The specific name medemi honors Fred Medem, collector of the holotype. Common name Medem giant glass frog has been coined for it.

Centrolene prosoblepon is a species of frog in the family Centrolenidae, commonly known as the emerald glass frog or Nicaragua giant glass frog. This species can be found in Ecuador, Colombia, Panama, Costa Rica, Nicaragua, and Honduras. Its natural habitats are lowland tropical forests and montane cloud forests. It is a nocturnal species occurring in low vegetation in mature forests only. It is not considered threatened overall by the IUCN although deforestation and pollution are potential threats, as is chytridiomycosis.
Centrolene sanchezi is a species of frog in the family Centrolenidae. It is found in the Andes mountains in Colombia and Ecuador. Its natural habitats are subtropical or tropical moist montane forests and rivers.
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.
Ameerega bilinguis, the Ecuador poison frog, is a species of frogs in the family Dendrobatidae found in Colombia, Ecuador, and possibly Peru.
Ameerega trivittata, formerly Epipedobates trivittatus, is a species of frog in the family Dendrobatidae commonly known as the three-striped poison frog. It is found in Bolivia, Brazil, Colombia, Guyana, Peru, Suriname, Venezuela, possibly Ecuador, and possibly French Guiana.
The Sierra Juarez brook frog is a species of frog in the family Hylidae endemic to Mexico. Its natural habitats are subtropical or tropical moist lowland forests, subtropical or tropical moist montane forests, and rivers. It is threatened by habitat loss and possibly by chytridiomycosis, and the IUCN has assessed its conservation status as near threatened.
Hyloscirtus alytolylax, called the babbling stream frog, babbling torrenter, or tadapi tree frog in English, is a species of frog in the family Hylidae found in Colombia and 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. Scientists have observed it in Colombia between 500 and 2159 meters above sea level and in Ecuador between 400 and 2000 meters above sea level.
The El Pepino tree frog is a species of frog in the family Hylidae found in Colombia and Ecuador. Its natural habitats are subtropical or tropical moist lowland forests, subtropical or tropical moist montane forests, rivers, and swamps. It is threatened by habitat loss.
Litoria havina is a species of frog in the subfamily Pelodryadinae. It is found in New Guinea.
Ranoidea wilcoxii, also known as the stony-creek frog, eastern stony creek frog, and Wilcox's frog, is a species of frog in the subfamily Pelodryadinae. It is endemic to Australia, being found solely on the eastern coast between Ingham, QLD, and Sydney, NSW, and as far west as Atherton, QLD. Its natural habitats are subtropical or tropical dry forests, subtropical or tropical moist lowland forests, rivers, intermittent rivers, and pastureland.
The cloud forest stream frog is a species of frog in the family Hylidae found in El Salvador, Guatemala, Mexico, and possibly Honduras. Its natural habitats are subtropical or tropical moist lowland forest, subtropical or tropical moist montane forest, and rivers. The cloud forest stream frog's lower elevation limit sits at 500 meters and it's upper elevation limit is at 2,200 meters. The frog's current population trend is suspected to be decreasing due to the ongoing degradation in the quality and extent of its environment. It is common in Guatemala and Mexico, but the population status in Honduras and El Salvador are unknown. It is threatened by habitat loss. These frogs are semiaquatic, living both terrestrially and in inland freshwater.
The smoky jungle frog is a species of frog in the family Leptodactylidae. It is found in northern South America as well as parts of Central America. Its natural habitats are tropical and subtropical moist broadleaf forests, subtropical or tropical swamps, subtropical or tropical moist montane forest, rivers, freshwater marshes, intermittent freshwater marshes, and aquaculture ponds.
Mantella madagascariensis, common names Malagasy painted mantella, Madagascan mantella, Madagascar golden frog, Malagasy mantella and painted mantella, is a species of frog in the family Mantellidae.
Pseudophilautus decoris, commonly known as the elegant shrub frog, is a species of frogs in the family Rhacophoridae. It is endemic to Sri Lanka.
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.
