The snow leopard, also known as the ounce, is a felid in the genus Panthera native to the mountain ranges of Central and South Asia. The snow leopard attains a length of about 7 feet. They are apex predators, which means that they sit at the top of the food chain and have no natural predators themselves. In captivity, snow leopards have been known to live for as long as 22 years. Life in the wild is much harder, so the life expectancy of wild snow leopards is more likely to be 10 to 12 years. There are an estimated 4,080-6,590 snow leopards left in the wild.
