The rarest big cat is the Amur leopard (panthera pardus ssp. orientalis). There are less than 30 left in the wild and the population is declining, which means they are critically endangered. They face various threats including habitat loss, poaching and climate change. The Amur leopard is a subspecies of leopard (panthera pardus) that includes the more familiar African leopard, which as a whole species is not as rare. At the species level, snow leopards (panthera uncia) are rarer, with an estimated 4,080-6,590 remaining. You can find out more about endangered species at the IUCN Red List website, found at
