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 tadpole A tadpole or polliwog (also spelled pollywog) is the Larva, larval stage in the biol ...

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 ca ... [...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 Endemism, endemic to the rainforest of the southern Amazon Basin in Brazil. Habitat The frog's natural habitats are tropical moist lowland forests, where it has been observed as high as 600 meters above sea level. It seems to prefer forest habitats with large numbers of Brazil nut trees. The eggs are laid on the ground. After the eggs hatch, the adult frogs carry the tadpoles to water. Scientists believe this may include water collected in Brazil nut husks. The frog's known range includes many protected areas. Threats The IUCN classifies this frog as least concern of extinction and notes that it has shown some tolerance to habitat disturbance. 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 hydroelectric dams. The species is relati ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
