15. Sure-footed horned beasts, called dall sheep live in subarctic climates.
The Dall sheep, also called the thin-horn sheep, comes in a wide range of colors and has curved brown horns. They live among the mountain ranges of Alaska, as well as regions of British Columbia. These beasts are found in mostly dry areas, feasting on plants and grasses. Their hooves make it perfect for them to escape from predators as they can easily climb rugged ground to get away. Their horns take up to eight years to grow and are composed of keratin, the same material as our fingernails. The age of the sheep can be calculated from the number of growth rings on their horns. They also use their horns for defensive purposes and have been known to butt grey wolves off cliffs. Their diet consists of mostly grasses, sedges, dwarf willows, and mosses. They also have a lot of predators and threats, including wolves, coyotes, and bears.
