"Bighorn Sheep," Wikipedia, the free encyclopedia. Bighorn sheep are named for the large, curved horns borne by the rams (males). Ewes (females) also have horns, but they are shorter with less curvature.[17] They range in color from light brown to grayish or dark, chocolate brown, with a white rump and lining on the backs of all four legs. Males typically weigh 127316 lb (58143 kg), are 3641 in (91104 cm) tall at the shoulder, and 6979 in (180200 cm) long from the nose to the tail. Females are typically 75188 lb (3485 kg), 3036 in (7691 cm) tall and 5467 in (140170 cm) long. Male bighorn sheep have large horn cores, enlarged cornual and frontal sinuses, and internal bony septa. These adaptations serve to protect the brain by absorbing the impact of clashes.
