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.

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] |

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 Quinquevittatus
''Adelphobates quinquevittatus'' (Rio Madeira poison frog or more ambiguously, Amazonian poison frog) is a species of frog in the family Dendrobatidae found in the Rio Madeira drainage in the southern Amazon Basin in Brazil and Bolivia. Most records of this species before 1990 refer to '' Ranitomeya ventrimaculata''. Its natural habitats are tropical moist lowland forests, freshwater marshes, and intermittent freshwater marshes. It is threatened by habitat loss Habitat destruction (also termed habitat loss and habitat reduction) is the process by which a natural habitat becomes incapable of supporting its native species. The organisms that previously inhabited the site are displaced or dead, thereby ....

Poison Dart Frogs
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 ...

Dendrobates
''Dendrobates'' is a genus of poison dart frogs native to Central and South America.

Excidobates Captivus
''Excidobates captivus'', the Santiago poison frog or Rio Santiago poison frog, is a species of frog in the family Dendrobatidae. It is endemic to northwestern Peru and southern Ecuador. Its natural habitat is tropical moist lowland forests. This frog is black with rows of orange-red spots on its back and yellow spots underneath. Description With an adult snout–vent length of , ''Excidobates captivus'' is a very small species of poison frog. It is black with orange-red splotches arranged in a row down either side of the back. It also has small yellow spots above the armpit and groin and further pale yellow spots beneath the chin and scattered on the chest and belly and under the thighs. The first finger of the forelimb is considerably shorter than the second finger. Distribution ''Excidobates captivus'' was first collected in 1929 from the south side of the Marañón River near its confluence with the Santiago River in northwestern Peru, a wet lowland site at an elevation of ab ...

Pumiliotoxin 251D
Pumiliotoxin 251D is a toxic organic compound. It is found in the skin of poison frogs from the genera ''Dendrobates'', ''Epipedobates'', '' Minyobates'', and ''Phyllobates'' and toads from the genus '' Melanophryniscus''. Its name comes from the pumiliotoxin family (PTXs) and its molecular mass of 251 Daltons. When the toxin enters the bloodstream through cuts in the skin or by ingestion, it can cause hyperactivity, convulsions, cardiac arrest and ultimately death. It is especially toxic to arthropods (e.g. mosquitoes), even at low (naturally occurring) concentrations. Chemical properties Structure The chiral centers in pumiliotoxin 251D can give several stereoisomers of the compound. Only one form of the toxin is present in nature and has toxic properties. Two enantiomers of pumiliotoxin 251D. On the left the plus enantiomer is shown which is toxic. On the right side the minus enantiomer, which is not toxic, is shown.
