Yaks are often used to haul gear for Mount Everest climbs. They can haul 100 kg (220 pounds), have thick fur and large lungs. One common piece of advice for those in the Everest region is to be on the higher ground when around yaks and other animals, as they can knock people off the mountain if standing on the downhill edge of a trail. Other animals in the region include the Himalayan tahr which is sometimes eaten by the snow leopard. The Himalayan black bear can be found up to about and the red panda is also present in the region. One expedition found a surprising range of species in the region including a pika and ten new species of ants.
