a huge and impossible hulk of an animal, the wild yak has stocky, high and humped shoulders and a broad, drooping head. Both males and females have horns, which grow out the sides of the head and curve upwards halfway along their length. The horns of females are shorter than those of males: females are also one third of the body size of males. for protection of the severe cold of Tibet, the wild yak has a dense undercoat of soft, closely-matted fur, covered by dark brown, long and shaggy fur.
