Leo 43M is one of the oldest Far Eastern leopards living in Land of the Leopard National Park. He was named after the village of Filippovka, Khasan District, where he was first spotted by trail cameras in 2009. In the first years of leopard photo monitoring, the animals were named after the closest village or town to the place where they were first seen.
Filippovsky is now about 12 years old. Despite his mature age, he often shows off his trim physique for the cameras.
