Context: Anomaloglossus baeobatrachus is a species of frog in the Aromobatidae family.  It is found in northern Brazil south to Manaus, French Guiana, and Suriname; it is expected to occur eastern Guyana.  It inhabits the leaf-litter of forests. Uperodon globulosus, or Indian balloon frog, is a species of narrow-mouthed frog found in India, Nepal, and Bangladesh.  It is known under many common names: Indian globular frog, Indian balloon frog, grey balloon frog, and greater balloon frog.  Specimens from the Western Ghats may represent an undescribed species. Microhyla berdmorei (common names: Berdmore's chorus frog, Berdmore's narrow-mouthed frog, Burmese microhylid frog, large pygmy frog, Pegu rice frog) is a species of narrow-mouthed frog found in eastern India, Bangladesh, southernmost China (Yunnan), Mainland Southeast Asia as well as Borneo and Sumatra.  Frogs from Bangladesh probably represent an unnamed species. The strawberry poison frog or strawberry poison-dart frog ("Oophaga pumilio", formerly "Dendrobates pumilio") 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. Fejervarya limnocharis is a species of frog found widely distributed in South Asia.  It is known under many common names, including Indian cricket frog, Boie's wart frog, rice field frog, and Asian grass frog.  Molecular studies of the species complex suggest that there may be multiple species involved. Manaus (] ] ) or Manaós before 1939 or (formerly) Barra do Rio Negro, is the capital city of the state of Amazonas in the North Region of Brazil.  It is situated near the confluence of the Negro and Solimões rivers.  With a population of more than 2 million, it is the most populous city of both the Brazilian state of Amazonas and the Amazon rainforest. The Seoul frog or Seoul pond frog ("Pelophylax chosenicus") is a species of true frog found on the southern and western Korean Peninsula, and possibly across the border to China in Liaoning.  It is closely related to the eastern golden frog, "P. plancyi", and was long considered a subspecies thereof.  Also known as gold-spotted pond frog, it is in fact not a true pond frog of genus "Rana", but belongs to the water frogs now again separated in "Pelophylax". Anomaloglossus lacrimosus is a species of frog in the Aromobatidae family.  It is endemic to western Colombia where it is known from the drainage of Atrato River, San Juan River, and Guanguí River.  It is a very rare frog found along streams in lowland and foothill forests and may be declining from threats such as deforestation for agriculture (including illegal crops), logging, human settlement and pollution from spraying of illegal crops.  The only conservation measure known is that it occurs in . Rana amurensis (Khabarovsk frog, Siberian wood frog, Heilongjiang brown frog or Amur brown frog) is a species of true frog found in northern Asia.

" Rana coreana" was previously included in this species as a subspecies. Hylarana temporalis, commonly known as the bronzed frog or Günther's golden-backed frog, is a species of true frog found in the riparian evergreen forests of the highlands of southwestern Sri Lanka.  They are found abundantly on or close to the ground near water.  Individuals are not shy and react by jumping only when provoked.  They are important prey of many species of snakes, including the vine snake.  Some related species found in the Western Ghats of India were formerly included in this species but were separated in a 2014 study.
