The Amur Leopard (Panthera pardus orientalis) holds the title of the world’s rarest big cat, formally recognised by the World Records Authority. With only an estimated 65–69 individuals remaining in the wild according to the most recent comprehensive census, this majestic predator is officially classified as Critically Endangered by the IUCN. Native exclusively to the temperate forests along the border of the Russian Far East and north-eastern China, the Amur Leopard is a powerful symbol of urgent global conservation efforts. Its preservation remains a paramount priority for biodiversity and the natural heritage of our world.
