YAK
Bos grunniens
DESCRIPTION
Yak (Bos grunniens) is commonly known as the domestic yak and the wild yak. These large, shaggy animals are well-adapted to the harsh, cold environments of the Himalayas and Tibetan Plateau. They have long, thick fur that helps insulate them against frigid temperatures, and their large, curved horns are used for defense and social interactions.
FUN FACTS
- Yaks are incredibly strong animals, capable of carrying heavy loads over long distances in rugged terrain
- They have been domesticated for thousands of years and are vital to the livelihoods of many pastoralist communities in the Himalayas
- | The thick fur of yaks is not only useful for insulation but is also used to make traditional clothing and blankets
- Their dung is often used as fuel for cooking and heating in remote areas, making them an essential resource for local populations
