True frogs is the common name for the frog family Ranidae. They have the widest distribution of any frog family. They are abundant throughout most of the world, occurring on all continents except Antarctica. The true frogs are present in North America, northern South America, Europe, Africa, and Asia. The Asian range extends across the East Indies to New Guinea and a single species, the Australian wood frog, has spread into the far north of Australia.
Amolops is a genus of true frogs native mainly to eastern and south-eastern Asia. These frogs are closely related to such genera as Huia, Meristogenys, Odorrana, Pelophylax and Rana, but still form a distinct lineage among the core radiation of true frogs. They are commonly known as "torrent frogs" after their favorite habitat - small rapid-flowing mountain and hill streams - but this name is used for many similar-looking frogs regardless of whether they are loosely related.
Meristogenys is a genus of true frogs from Borneo. Its tadpoles are adapted to fast-flowing mountain streams and easily recognizable by their divided upper lip with ribs on the outside.
Odorrana tormota, also known as the concave-eared torrent frog, is a species of frog native to China. Its distribution is restricted to Huangshan Mountains in Anhui and Jiande and Anji counties in northern Zhejiang. It occurs in fast-flowing streams and the surrounding habitats, and breeds in streams. The informally assigned common name for frogs in this genus is torrent frog.
Amolops monticola is a species of frog in the family Ranidae, the "true frogs". It is found in the Northeast India, eastern Nepal, and western China, although there is some uncertainty regarding the Chinese records. It probably also occurs in the intervening Bhutan. Common names mountain sucker frog, mountain stream frog, mountain torrent frog, and mountain cascade frog have been coined for it.
Hose's frog is a true frog species with a wide range in Southeast Asia. This species was named after zoologist Charles Hose.
Torrent frogs are a number of unrelated frogs that prefer to inhabit small rapid-flowing mountain or hill streams with a lot of torrents. They are generally smallish neobatrachians with a greyish-brown and usually darkly mottled back, giving them excellent camouflage among wet rocks overgrown with algae; their well-developed feet make them agile climbers of slippery rocks.
Amolops hainanensis is a species of frog in the family Ranidae that is endemic to southwestern and central Hainan, China. Its natural habitats are subtropical or tropical moist lowland forests and rivers. It is threatened by habitat loss. It is a sister taxa to both A. torrentis and A. daiyunnensis.
Amolops ricketti is a species of frog in the family Ranidae that is found in southern and eastern China and northern and central montane Vietnam.
The Javan torrent frog is a species of frog in the family Ranidae. It is endemic to Java, Indonesia. It is found in Mount Halimun Salak National Park, Ujung Kulon National Park, and Gunung Gede Pangrango National Park in West Java, as well as in Dieng Nature Reserve in Central Java.
The Siamese cascade frog or spotted-snout frog is a species of frogs in the family Ranidae. It is endemic to western and northern Thailand and known from Kanchanaburi, Prachuap Kiri Khan, and Chiang Mai Provinces.
The Sumatran torrent frog is a species of frog in the family Ranidae. It is endemic to Indonesia. The informally assigned common name for frogs in this genus is torrent frog.
Meristogenys phaeomerus is a species of frog in the family Ranidae. It is endemic to Borneo and known from central Sarawak (Malaysia) and adjacent Kalimantan (Indonesia). The specific name phaeomerus is derived from the Greek phaios for "dusky" and meros for "thigh", in reference to the appearance of the rear of the thigh. Common names Kapit Borneo frog and Kapit torrent frog have been coined for it.
Nannophrys ceylonensis, commonly known as the Sri Lanka rock frog or the Ceylon streamlined frog, is a species of frog. It used to be placed in the large frog family Ranidae but a phylogenetic study was undertaken using DNA sequences and it is now included in the family Dicroglossidae. It is endemic to Sri Lanka where its natural habitats are subtropical or tropical moist lowland forests, subtropical or tropical moist montane forests, rivers and streams.
Amolops daorum is a species of frog in the family Ranidae. It is known from its type locality in the vicinity of Sa Pa in northern Vietnam near the Chinese border, Hong Kong, and Houaphanh Province in eastern Laos; presumably it also occurs the intervening areas. The Hong Kong record is considered suspicious, however.
The common green frog is a frog species of in the true frog family Ranidae; some sources still use the old name Rana erythraea. It lives in Southeast Asia and is also known as green paddy frog, red-eared frog or leaf frog. The last name, however, commonly refers to the Neotropical tree frogs which make up the subfamily Phyllomedusinae. These are not closely related to H. erythraea, belonging to family Hylidae instead.
Odorrana graminea, the large odorous frog, inhabits fast-flowing streams in elevated mountainous regions of Southern China and Northern Indochina. It is one of 56 species in the genus Odorrana. Male O. graminea are noted for their ultrasonic call characteristics and are one of three frog species able to detect ultrasonic frequencies, likely evolved to facilitate communication amidst noisy streams and waterfalls. Studies on O. graminea courtship vocalizations suggest female preference for increased proportion of nonlinear vocal phenomena (NLP).
Humerana lateralis is a species of frog in the family Ranidae. It is found in Cambodia, Laos, Myanmar, Thailand, and Vietnam. It is commonly known as Kokarit frog, yellow frog or (ambiguously) wood frog.
Odorrana, commonly known as odorous frogs, is a genus of true frogs (Ranidae) from East Asia and surrounding regions. Many of these frogs inhabit fast-flowing mountain streams, and they typically have a remarkably pointed snout, as evidenced by common names like tip-nosed frog and scientific names like nasica or nasutus.
Wijayarana is a group of true frogs found in Southeast Asia. Their common name is Wijaya cascade frogs. Many are commonly known as "torrent frogs" after their favorite habitat - small rapid-flowing mountain and hill streams -, but this name is used for many similar-looking frogs regardless of whether they are closely related.
