The world's most endangered species of cat has seen a significant population increase in recent years.
While estimates had previously suggested that there were only around 40 individuals left, new figures from authorities in China and Russia have indicated that there could now be as many as 80.
Most of the remaining cats are located in Russia with a few also surviving in parts of China.
"The scientists shared some of the monitoring material at a meeting held in the Land of Leopard National Park's Vladivostok office," a park spokesman said in a statement. "The count of unique animals showed that the world population of the Far Eastern leopard was at least 80 animals."
Some extremely rare trail-cam recordings of the leopards in the wild can be viewed below.
