Nanorana parkeri (common names: High Himalaya frog, Xizang Plateau frog, Parker's slow frog, mountain slow frog) is a species of frog in the family Dicroglossidae. It is found in Tibet (China) and in Nepal, but it is expected to be found also in Bhutan and parts of India.[2] It is the second amphibian, and the first Neobatrachian, to have its whole genome sequenced.[3]

Description

Nanorana parkeri are medium-sized frogs: males grow to a snout–vent length of about 44 mm (1.7 in) and females to 48 mm (1.9 in). Tadpoles are up to about 51 mm (2.0 in) in length.[4]

Genome

The genome is about 2.3 Gb in size, encoding more than 20,000 protein-coding genes. Nanorana parkeri is estimated to have diverged from Xenopus tropicalis, the other amphibian with sequenced genome, approximately 266 Ma ago (range 134–311 Ma).[3]

Habitat and conservation

This very common frog is found on high-altitude grasslands, forests, shrubs, lakes, ponds, marshes, streams and rivers in the Tibetan Plateau at elevations of 2,850–5,000 m (9,350–16,400 ft) asl. It an explosive breed in streams and marshes. There are no known major threats.[1]
