Mountain weasel is a species that belongs to the Mustelidae family and is commonly found in the mountainous regions of Central Asia. The term "mountain weasel" is sometimes used interchangeably with other names such as the Lesser Weasel, Himalayan Weasel, and Yellow-bellied Weasel. The Lesser Weasel is the smallest and lightest member of the weasel family, and its yellowish-brown fur and white belly distinguish it from other members of the family. The Himalayan weasel, on the other hand, is larger with a darker coat and is found at higher altitudes. The Yellow-bellied weasel is known for its bright yellow underbelly and darker coat. While these species may differ slightly, they are all classified as mountain weasels, and are adapted to life in the mountains.
