The polkadot poison frog (Oophaga arborea) is a species of frogs in the family Dendrobatidae endemic to Panama, [2] where it is known as rana venenosa in Spanish. Its natural habitats are humid lowland and montane forests. It is threatened by habitat loss and is listed by the IUCN as being "critically endangered". [1]
The snout-to-vent length of the polkadot poison frog is 20 to 22 mm (0.8 to 0.9 in). The hind limbs are short and the forelimbs relatively long with large hands. The fingers are unwebbed, the second one being longer than the first, and all but the first finger have flat discs of thickened skin. This frog has brown eyes and no teeth in its upper jaw. Males have a small vocal sac on the throat, and when not in use, this hangs in folds. The skin on the belly and inside the thighs is coarsely wrinkled. This frog is black or some shade of brown with roundish yellow spots, which often have a raised surface. The call made by the male is similar to that of closely related species but can be distinguished by its pitch, duration and the length of time between successive calls. [3]
This species is most closely related to e O. pumilio , O. sylvatica , O. speciosa , and O. granulifera . [4]
The polkadot poison frog is arboreal in its habits, living among the mosses and epiphytic plants growing on trees in the dense forests of western Panama at altitudes of up to 1,120 metres (3,670 ft) above sea level. The male typically chooses the leaf of a bromeliad plant on which to call to attract a mate. If receptive, the female joins him in a courtship ritual after which a small batch of about four to eight eggs is laid on the leaf and fertilised by the male. The female remains with the eggs for a short time after which the male covers them with his body. [3] The newly hatched tadpoles are carried to water bodies, such as pools forming in the rosettes of bromeliads, where they develop. [3]
The total extent of occurrence of the polkadot poison frog is less than 5,000 square kilometres (1,900 sq mi), and even within this range, there are a number of separate subpopulations. The population trend of this frog is unknown but the forests in which it lives are being affected by logging. Another factor limiting its numbers may be collection for the pet trade, and it may be susceptible to the disease chytridiomycosis. However, part of its range is within the bounds of the Parque Internacional La Amistad and the Bosque Protector Palo Seco. Taking these various factors into account, the IUCN has listed the conservation status of this species as "critically endangered". [1]
The strawberry poison frog, strawberry poison-dart frog or blue jeans poison frog is a species of small poison dart frog found in Central America. It is common throughout its range, which extends from eastern central Nicaragua through Costa Rica and northwestern Panama. The species is often found in humid lowlands and premontane forest, but large populations are also found in disturbed areas such as plantations. The strawberry poison frog is perhaps most famous for its widespread variation in coloration, comprising approximately 15–30 color morphs, most of which are presumed to be true-breeding. O. pumilio, while not the most poisonous of the dendrobatids, is the most toxic member of its genus.
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.
The harlequin poison frog, also known as harlequin poison-dart frog, is a species of poison dart frog endemic to the Chocó region of western Colombia. The frog is normally found on the ground of tropical rain forests, among fallen limbs or leaf litter. Some frogs traditionally classified as Oophaga histrionica were separated as new species in 2018. These are Oophaga anchicayensis, Oophaga andresi and Oophaga solanensis.
The sky-blue poison frog is a species of poison dart frog. It is endemic to Peru and known from the lower eastern versant of the Andes in the upper Amazon basin of the San Martín Region.
Dendrobates is a genus of poison dart frogs native to Central and South America. It once contained numerous species, but most originally placed in this genus have been split off into other genera such as Adelphobates, Ameerega, Andinobates, Epipedobates, Excidobates, Oophaga, Phyllobates and Ranitomeya, leaving only five large to medium-sized species in the genus Dendrobates. All the other genera used to be grouped in with Dendrobates because it was previously thought that all brightly colored poison dart frogs came from the same ancestor but this has since been proven to be incorrect. Dendrobates and Phyllobates evolved conspicuous coloration from the same common ancestor but not the same as any of the other genera listed above.
Epipedobates is a genus of poison dart frogs native to northern South America west of the Andes, including the western slopes. Common name phantasmal poison frogs has been suggested for the genus.
The Aromobatidae are a family of frogs native to Central and South America. They are sometimes referred to as cryptic forest frogs or cryptic poison frogs. They are the sister taxon of the Dendrobatidae, the poison dart frogs, but are not as toxic as most dendrobatids are.
The granular poison frog or granular poison arrow frog is a species of frog in the family Dendrobatidae, found in Costa Rica and Panama. Originally described as Dendrobates granuliferus, it was moved to Oophaga in 1994. Its natural habitats are tropical humid lowland forests; it is threatened by habitat loss.
Lehmann's poison frog or the red-banded poison frog is a species of frogs in the family Dendrobatidae endemic to a small part of western Colombia. Its natural habitats are submontane tropical rainforests. It is threatened by habitat loss and collection for the pet trade, and the IUCN lists it as being "critically endangered". It was named after Colombian conservation biologist Federico Carlos Lehmann.
The blue-bellied poison frog or bluebelly poison frog is a species of frog in the family Dendrobatidae.
Vicente's poison frog is a species of frog in the family Dendrobatidae that is endemic to the Veraguas and Coclé Provinces of central Panama. It is a little known arboreal frog that inhabits humid tropical lowland and montane forest.
The pleasing poison frog is a species of frog in the family Dendrobatidae endemic to Peru. The specific name bassleri honors Harvey Bassler, an American geologist and paleontologist.
The Cainarachi poison frog is a species of frogs in the family Dendrobatidae. It is endemic to Amazonian Peru and found in the lowlands adjacent to the northern end of the Eastern Andes. It was named after the Rio Cainarache Valley, where it was first discovered.
The Manú poison frog is a frog species in the family Dendrobatidae found in southern Peru and Brazil. It can be found in the drainages of the Manú, Urubamba, Upper Purus and Ucayali Rivers. It can also be found in Serra do Divisor National Park and Alto Juruá Extractive Reserve.
The Peru poison frog, also known as Peruvian poison frog, Peruvian poison-arrow frog and emerald poison frog, is a species of frog in the family Dendrobatidae. It is found in eastern Peru and western Brazil. Its natural habitats are primary premontane and subtropical or tropical moist lowland forests, rivers, freshwater marshes, and intermittent freshwater marshes.
The Oxapampa poison frog is a species of frog in the family Dendrobatidae endemic to Peru near Oxapampa, in the Pasco Region. Its natural habitat is montane tropical rainforest. It is a very rare species threatened by habitat loss.
Oophaga is a genus of poison-dart frogs containing twelve species, many of which were formerly placed in the genus Dendrobates. The frogs are distributed in Central and South America, from Nicaragua through the Colombian El Choco to northern Ecuador. Their habitats vary with some species being arboreal while other being terrestrial, but the common feature is that their tadpoles are obligate egg feeders.
Adelphobates is a small genus of poison dart frogs. They are found in the central and lower Amazon basin of Peru and Brazil, possibly Bolivia. It was originally erected as a sister group to the Dendrobates and Oophaga genera. The validity of the genus is still being discussed, with the alternative being "Dendrobates galactonotus group" within Dendrobates. One species originally placed in this genus as Adelphobates captivus has since been moved to the genus Excidobates erected in 2008.
Ranitomeya is a genus of dart poison frogs found in Panama and South America south to Peru and Brazil, possibly into Bolivia.
Dendrobatinae is the main subfamily of frogs in the family Dendrobatidae, the poison dart frogs of Central and South America, found from Nicaragua to the Amazon basin in Brazil.
