Dendrobatinae
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. Description Dendrobatinae are generally small frogs; '' Andinobates minutus'' is as small as in snout–vent length. Many species are brightly colored and all are toxic. Alkaloids in '' Phyllobates'' are particularly potent. All species are presumed to show parental care, often by the male. However, some species show biparental care ('' Ranitomeya''), whereas in '' Oophaga'' only females care for the tadpoles, feeding them with eggs, their only source of nutrition. The males are responsible for protecting the eggs from predation and keeping the eggs from drying out by urinating on them.Brust, D. G.

Adelphobates
''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. Etymology ''Adelphobates'' is from the Ancient Greek, ''adelphos'' (brother or twin) and ''bates'' (walker or climber)."Brothers" refers to Charles W. Myers and John W. Daly, two unrelated scientists directly involved with studies of the species. Biology All members have conspicuous, vibrant coloration, and smooth skin. A peculiar feature of their reproduction is that tadpoles are transported to Brazil nut The Brazil nut (''Bertholletia excelsa'') is a South America ...

Adelphobates Galactonotus
''Adelphobates galactonotus'' (splash-backed poison frog or splashback poison frog) is a species of poison dart frog. It is endemic to the rainforest of the southern Amazon Basin in Brazil. Its natural habitats are tropical moist lowland forests. The eggs are laid on the ground, but the tadpoles are carried to temporary pools. Though it remains widespread and locally common, it is threatened by habitat loss and has already disappeared from some localities due to deforestation and flooding caused by dams. The species is relatively common in captivity and regularly bred, but the wild populations are still at risk from illegal collection. The best known variants of this species are black below and yellow, orange or red above, but its color is extremely variable with some having whitish-mint or light blue upperparts, some having a mottled or spotted pattern above, and some being almost all whitish (popularly known as "moonshine" among captive frog keepers), yellow-orange or black.

Adelphobates Castaneoticus
The Brazil-nut poison frog (''Adelphobates castaneoticus'') is a species of frog in the family Dendrobatidae. It is endemic to the state of Pará in Brazil. The frog is believed to have received its common name from the fact that its tadpoles sometimes develop in the hard capsules of the Brazil nut tree, which are common in its range. The nuts fall to the forest floor where they are broken open by agoutis and other animals seeking the seeds, and empty husks fill with water. Description The Brazil-nut poison frog is a very small frog with a snout-to-vent length of ; females are usually larger than males. The dorsal surface is of a shiny black colour with spots and markings of white or various shades of yellow. There is a bright yellow or orange spot where the foreleg joins the body and two more similarly coloured spots on either side of the knee joint on the hind leg, which combine to make a single large spot when the animal is stationary. A further spot on the underside of the cal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Andinobates Minutus
The blue-bellied poison frog or bluebelly poison frog (''Andinobates minutus'') is a species of frog in the family Dendrobatidae. Dart-poison frogs (Dendrobatidae) form the most diverse group of diurnal frogs in the Neotropics, diminutive animals that possess aposematic coloration and toxic skin secretions. Taxonomic problems among these frogs are often caused by color polymorphisms which are common within and between species; thus molecular genetics, bioacoustics, ecological and behavioral data have been applied recently to solve many taxonomic problem within the family. It is found in Colombia and Panama. The range of this species within Panama and Colombia goes from Panama (within El Valle and Cerro Campana, in the central areas of the country and the eastern lowlands and cordilleras), south to Colombia (south to Rio Saija). It occurs below 1,000m, generally even lower. Its natural habitats are tropical moist lowland forests. It is a locally abundant, terrestrial species. As ...

Ranitomeya Dorisswansonae02
''Ranitomeya'' is a genus of dart poison frogs found in Panama and South America south to Peru and Brazil, possibly into Bolivia. Taxonomy In 2006 Grant ''et al.'' revised the systematics of poison dart frogs and placed many species formerly classified in the genera ''Dendrobates'', '' Minyobates'' and '' Phyllobates'' in ''Ranitomeya''. In 2011 Brown and colleagues, following other scientists who assumed the existence of two distinct clades in ''Ranitomeya'', erected the genus ''Andinobates'' for 12 species of ''Ranitomeya''. ''Ranitomeya'' and ''Andinobates'' frogs can be distinguished from those in genera such as ''Dendrobates'' in that they are generally smaller, have more than two colors, and seem to glitter if viewed from certain angles. ''Ranitomeya'' is widespread in the Amazon basin The Amazon basin is the part of South America drained by the Amazon River and its tributaries. The Amazon drainage basin covers an area of about , or about 35.5 percent of the Sou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Andinobates Abditus
''Andinobates abditus'' is a species of poison dart frog, sometimes known as the Collins' poison frog. It is endemic to Ecuador where it is only known from its type locality, at the eastern base of the Reventador volcano, in the Napo Province. ''Andinobates abditus'' no longer survives in its type locality, although it is possible that it occurs elsewhere (including the nearby Cayambe Coca Ecological Reserve Cayambe Coca National Park is a national park in Ecuador located along the Equator about from Quito. The park encompasses an area of . The reserve The park includes two very different regions of Ecuador, the high altitude sierra with Cayambe ..., but its presence there has not been confirmed). The disappearance from the type locality was due to habitat loss, possibly together '' Batrachochytrium dendrobatidis'' infection. The type locality was characterized by dense, humid forest with many mosses and epiphytes. References Amphibians described in 1976 Andinobat ...

Poison Dart Frog
Poison dart frog (also known as dart-poison frog, poison frog or formerly known as poison arrow frog) is the common name of a group of frogs in the family Dendrobatidae which are native to tropical Central and South America. These species are diurnal and often have brightly colored bodies. This bright coloration is correlated with the toxicity of the species, making them aposematic. Some species of the family Dendrobatidae exhibit extremely bright coloration along with high toxicity, while others have cryptic coloration with minimal to no amount of observed toxicity. The species that have great toxicity derive this feature from their diet of ants, mites and termites. However, other species that exhibit cryptic coloration, and low to no amounts of toxicity, eat a much larger variety of prey. Many species of this family are threatened due to human infrastructure encroaching on their habitats. These amphibians are often called "dart frogs" due to the Native Americans' use of the ...

Andinobates Cassidyhornae
''Andinobates'' is a genus of poison dart frogs from Ecuador, Colombia and Panama. It contains species formerly classified in the genus ''Dendrobates'' and in 2006 transferred to the genus ''Ranitomeya''. In 2011 Twomey, Brown, and their colleagues erected the genus ''Andinobates'' for a group of 12 species of ''Ranitomeya''. ''Andinobates'' frogs can be distinguished from their sister taxon ''Ranitomeya'' anatomically in that their 2nd and 3rd vertebrae are fused. They show no limb reticulation, which is present in most species of ''Ranitomeya''. Distribution ''Andinobates'' inhabits the rainforests of Ecuador, Colombia, and Panama Panama ( , ; es, link=no, Panamá ), officially the Republic of Panama ( es, República de Panamá), is a transcontinental country spanning the southern part of North America and the northern part of South America.

Oophaga
''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 (at elevations below ). Their habitats vary with some species being arboreal while other being terrestrial, but the common feature is that their tadpoles are obligate egg feeders. Etymology ''Oophaga'', Greek for "egg eater" (''oon'', '), is descriptive of the tadpoles' diet.Zimmermann, E. and Zimmermann, H. 1994.
