What are the physical adaptations of a yak?

Yaks have several physical adaptations that enable them to thrive in harsh high-altitude environments. Their long, thick fur provides insulation against cold temperatures, while their stocky build and short legs help conserve heat. Yaks also possess large lungs and a powerful heart to efficiently process oxygen in thin air, and their wide hooves are adapted for navigating rocky, uneven terrain. Additionally, their fat storage is essential for energy during the long, harsh winters.
