55. Bighorn Sheep
The bighorn sheep is a specific species of sheep native to the continent. They’re aptly named for their massive horns. A pair of bighorn sheep horns can weigh as much as 30 pounds. Ewes, or females, also have horns but they are not as curved and are shorter.
The sheep can weigh as much as 316 pounds. The male’s horns are both a status symbol and a weapon employed in territorial disputes. You can spot them in such places as Utah’s Zion National Park and Colorado’s Rocky Mountain National Park.
