A male markhor's horns can grow to 1.6 metres long - the same height as a tall child. The horns twist tightly in a spiral, which makes them very strong. The males use their horns to gently push each other in spring, deciding who gets to lead a small group of females and babies.
Markhor live on cliffs so steep that almost nothing else can climb them. They have special hooves with hard sharp edges and soft rubber-like pads in the middle, which grip the rock like climbing shoes. Babies are running and jumping up cliffs within days of being born.
The name 'markhor' comes from two old Persian words - 'mar' meaning snake, and 'khor' meaning eater. Old stories said the markhor was so clever it could even eat snakes. Nobody has ever actually seen one do that - they eat grass, leaves and herbs - but the name stuck.
Markhor used to be very rare, but careful protection in Pakistan has helped them come back. Today there are about 5,000 markhor living in the mountains, and the country is proud of saving them. The picture of a markhor appears on Pakistani money and the badges of mountain rescue teams.
