(Scutiger boulengeri)
Scutiger boulengeri (common names: Boulenger's lazy toad, Boulenger's high altitude toad, Himalayan stream frog, and Xizang alpine toad) is a species of toad in the family Bufonidae. It is found in Nepal, India (Sikkim) and western China (Sichuan, Yunnan, Gansu, Qinghai, and Tibet). A healthy population has been found at an elevation of 5,270 m (17,290 ft) in one of the lakes in the Gurudongmar Lake complex in Sikkimese Himalaya. This is one of the highest elevations where amphibians have ever been recorded ( Pleurodema marmoratum has been recorded higher at the Andes).
