The snow leopard is Panthera uncia or Uncia uncia, a separate species from Panthera pardus, the leopard. Snow leopards have black rosettes on long, thick whitish or buff fur, and they blend well into the snow and rock of the mountains of India, China, and Central Asia. They had never been photographed until 1970. They are solitary, preferring dawn and dusk, and must range widely to find enough food (mountain sheep, ibex, musk deer, wild boar, and marmot, for example, though they will eat domestic livestock if no wild prey is available). They are also suffering habitat depletion and are also hunted for their fur; there may be as few as 4,000 left in the wild.
