Description

Adult males measure 62–81 mm (2.4–3.2 in) and adult females 61–78 mm (2.4–3.1 in) in snout–vent length, [3] although Jiang and colleagues report a much lower range for males, 60–72 mm (2.4–2.8 in). [4] The head is broad and depressed. The tympanum is small and hidden under skin. The toes are partially webbed. [3] Males have nuptial spines on the first and second fingers, as well as two well-developed chest glands covered by strong spines. [5] No vocal sac is present. [4]

The tadpoles are adapted to running water and have elongated, dorso-ventrally flattened bodies and long tails. They grow to a total length of 80 mm (3.1 in), of which the body makes about one third. [5]

Habitat and conservation

Scutiger mammatus lives in small to medium-sized low-gradient streams, seepages, and spring-fed marshes in sub-alpine and alpine areas at elevations of 2,600–4,200 m (8,500–13,800 ft) above sea level. It is a very common species. Threats to it are unknown, but overgrazing is a potential threat. There are many protected areas within its range. [1]
