Location: Khumbu region of Nepal
This strong animal called as Zopkey is the hybrid of Yak and cow. Yak cannot bear the heat, but zopkey is able to accept both the lower and higher altitude i. e. able to tackle with cold and heat. Yaks cannot come lower than Namche 3445 meter, higher is better for them. But, zopkeys can tackle higher and lower elevations. Many tourists think that they have seen Yak in Lukla, but it is not. That is the hybrid, the Zopkey. Yaks can be seen above Namche, only.
