What do yaks have to help them survive?

Yaks have several adaptations that help them survive in harsh, high-altitude environments. Their thick, long fur provides insulation against cold temperatures, while their large lungs and heart support efficient oxygen intake in thin air. Additionally, yaks possess a unique digestive system that allows them to break down tough grasses and other fibrous plants, which are abundant in their mountainous habitats. Their sturdy bodies and strong hooves enable them to navigate rocky terrain with ease.
