The mountain weasel (Mustela altaica), also known as the pale weasel, Altai weasel or solongoi, primarily lives in high-altitude environments, as well as rocky tundra and grassy woodlands. This weasel rests in rock crevices, tree trunks, and abandoned burrows of other animals or the animals it previously hunted. The home range size of this animal is currently unknown. Geographical distribution for this species lies in parts of Asia from Kazakhstan, Tibet, and the Himalayas to Mongolia, northeastern China, southern Siberia, Korea, and also some parts of Russia. The most common area for this species, however, is Ladakh, India. The conservation status, according to the IUNC, is near threatened because it is considered to be in a significant decline and requires monitoring mainly because of habitat and resource loss.
Sexual dimorphism is slight in the Altai weasel. The male body length from head to base of the tail is about 8.5–11 in (220–280 mm), with the tail adding about 4–6 in (100–150 mm). Males can weigh 8–12 oz (230–340 g). Females are slightly smaller, with their head and body lengths measuring around 8.5–10 in (220–250 mm), with their tails adding 3.5–5 in (89–127 mm), and they weigh about 4–8 oz (110–230 g). This species undergoes seasonal molts during the spring and autumn. The summer coat consists of gray to gray-brown fur with some light yellow, while the winter fur is more of a dark yellow with some brown. In both coats, the underbelly is pale yellow to creamy white. The upper head between the muzzle and ears is usually darker gray-brown. The tail may be more rufous than the back. The summer fur is gray to gray-brown with some light yellow. The lips are white and the chin has grayish-brown vibrissae.
