As part of 1111′s A-Z of Creatures. Y is for Yak. Native to the alpine and tundra regions of central and northern Asia, the Yak is a shaggy haired bovid that has been domesticated by humans. Yaks will suffer from heat exhaustion at temperatures above 15′C (59′F). If you want to see your favorite animal starting with Z next week, drop a comment on the 1111 Animal’s facebook page.
