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]
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]
