Odorrana graminea
Habitat
Fast-flowing streams in elevated mountainous regions
Range
Southern China and northern Indochina

The large odorous frog inhabits fast-flowing streams in elevated mountainous regions of southern China and northern Indochina. Females are relatively large, at 78–100mm snout–vent, while males reach only 42–53mm. The back is green with smooth skin, and the flanks are brown with yellow marbling (Wikipedia, general species account).
Males are noted for ultrasonic calls and are one of three frog species able to detect ultrasonic frequencies above 20kHz, probably evolved to allow communication amid noisy streams and waterfalls (Wikipedia, general species account).
