Photo by Matthieu Paley @paleyphoto | A group of Bactrian camels after a snow storm. These beasts of nature are native to the steppes of Central Asia, where they have been used as pack animals along the Silk Road since ancient times. They have an incredible tolerance for cold, high altitude, and drought, belonging to a small group of animals that regularly eat snow to meet their water needs. The latent heat of snow and ice is enormous compared with the heat capacity of water, demanding a large sacrifice in heat energy and forcing animals to eat only small amounts at a time. #pamirmountains #bactriancamel #camel #afghanistan #centralasia
