THINHORN SHEEP
Ovis dalli
DESCRIPTION
Thinhorn Sheep (Ovis dalli), also known as Dall Sheep, is a species of wild sheep found in the mountainous regions of North America. They are characterized by their white or light cream-colored coats, which provide excellent camouflage against the rocky terrain. These sheep are social animals, often found in groups, and are known for their agility and ability to navigate steep, rugged landscapes.
FUN FACTS
- Thinhorn Sheep are remarkable climbers, capable of navigating steep cliffs and rocky outcrops with ease
- Their specialized hooves provide excellent traction, allowing them to traverse challenging terrains that would be difficult for other animals
- | The horns of male Thinhorn Sheep can weigh up to 14 kg and can grow to over 1 meter in length
- These impressive horns are not only used for display during mating season but also for defense against predators and rival males
