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 Megophryidae. It is found in Nepal, India (Sikkim), and western China (Sichuan, Yunnan, Gansu, Qinghai, and Tibet).[2]
Description
[edit]Scutiger boulengeri males measure about 45–55 mm (1.8–2.2 in) and females about 50–62 mm (2.0–2.4 in) in snout–vent length.[3][4] The head is flat, wider than long, and with a rounded snout. The eyes are protruding. The tympanum is indistinct; the supratympanal fold is present. The dorsum is olive or greenish-grey with numerous warts. The ventrum is yellowish. The fingers have no webbing and the toes have rudimentary webbing.[5]
Tadpoles grow to a length of about 60 mm (2.4 in).[4]
Habitat and conservation
[edit]Scutiger boulengeri is an alpine species that lives near streams and lakes in grassland habitats at elevations of 3,300–5,270 m (10,830–17,290 ft) above sea level.[1] A healthy population has been found at an elevation of 5,270 m (17,290 ft) in the Gurudongmar Lake complex in Sikkimese Himalaya.[3] This is one of the highest elevations where amphibians have ever been recorded. They hibernate in loose soil from September to March or April.[3]
Scutiger boulengeri is not considered threatened and is ranked as a species of least concern by the IUCN Red List.[1]
