Torrent frog

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.
