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.
Sachatamia ilex is a species of frog in the family Centrolenidae. It is found in eastern Nicaragua, Costa Rica, Panama, western Colombia, and western Ecuador. Common name Limon giant glass frog has been coined for this species, apparently in reference to its type locality in the canton of Limón, Costa Rica, and it is also known as the ghost glass frog.
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.
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.

It is found in northern Ecuador, Pacific lowlands and western slopes of the Cordillera Occidental in Colombia, and eastern Panama. It occurs from near sea level to 1,560 m (5,120 ft) asl.
Hyalinobatrachium chirripoi is a species of frog in the family Centrolenidae. It is found in extreme northern Ecuador, northwestern Colombia, Panama, and Costa Rica, as well as in Honduras.

Hyalinobatrachium colymbiphyllum, also called the bare-hearted glass frog, plantation glass frog and the cricket glass frog, is a species of frog in the family Centrolenidae that is found in moist forests, often near streams, in countries in Central America and South America. They are small, green frogs with many similarities to other glass frogs, however, they have the most transparent undersides of any glass frogs. Their transparent undersides make them ideal bio-indicators for how global warming and other threats are affecting the animals in the forests.
Hyalinobatrachium fleischmanni, also known as Fleischmann's glass frog or the northern glass frog, is a species of frog in the family Centrolenidae. It is found in the tropical Americas from southern Mexico to Ecuador. Specifically, these frogs occur in Mexico, Belize, Costa Rica, El Salvador, Guatemala, Honduras, Nicaragua, and Panama, Colombia, and Ecuador. Notice that this and related species have often been confused with each other, and the exact distribution depends on the source. This frog tends to have green skin, pale yellowish spots, yellow fingertips and translucent skin covering its stomach.
Hyalinobatrachium orientale is a species of glass frog in the family Centrolenidae. It is found on the island of Tobago and in eastern Venezuela. Its common name is eastern glass frog. The Tobagonian population has been described as subspecies Hyalinobatrachium orientalis tobagoensis(Hardy, 1984). The latter is sometimes referred to as Tobago glass frog. H. orientale is distributed throughout the Central Eastern ranges of the Cordillera de la Costa in Venezuela and Tobago Island with an altitudinal range of 190 to 1200 meters.

Hyalinobatrachium talamancae is a species of frog in the family Centrolenidae. It is endemic to the Limón Province, Costa Rica. Its common name is Talamanca glass frog. Its natural habitats are premontane wet forests. It is a regularly seen frog in suitable habitat.
Hyalinobatrachium vireovittatum is a species of frog in the family Centrolenidae. It is found in scattered localities in Costa Rica and west-central Panama. It has, however, been suggested that most populations actually represent Hyalinobatrachium talamancae, with Hyalinobatrachium vireovittatum restricted to its type locality in the San Isidro de El General district.
Silverstoneia nubicola is a species of frog in the family Dendrobatidae. It is found in western Colombia, Panama, and southwestern Costa Rica.
Allobates talamancae is a species of frog in the family Aromobatidae. It is found in northwestern Ecuador, western Colombia, Panama, Costa Rica, and southern Nicaragua.
The La Loma tree frog is a species of frog in the family Hylidae found in Costa Rica, Panama, and expected but not confirmed in Colombia. Its natural habitats are tropical moist lowland and montane forests, with breeding taking place in streams. It is threatened by habitat loss and chytridiomycosis.
Pristimantis altae, also known as mountain robber frog, is a species of rain frog in the family Strabomantidae with a bright coral-coloured groin. It is found in Costa Rica and Panama.
Pristimantis caryophyllaceus is a species of frog in the family Strabomantidae. It is found in Costa Rica and Panama; records from Colombia prior to 2010 refer to Pristimantis educatoris. However, taxonomy of Pristimantis caryophyllaceus and P. educatoris remain unsettled, and many sources continue to report Pristimantis caryophyllaceus from Colombia.
Pristimantis gaigei, also known as Fort Randolph robber frog or Gaige's rain frog, is a species of frog in the family Strabomantidae. It is found in the Atlantic drainage lowlands from extreme south-eastern Costa Rica to eastern Panama and to central Colombia; it is widely distributed in Colombia west of the Cordillera Oriental. Its natural habitat is primary humid lowland forest, but it also occurs in secondary forest. It is a nocturnal species found under surface debris and in leaf-litter.
