The leopard (Panthera pardus) is one of the five extant species in the genus Panthera. It has a pale yellowish to dark golden fur with dark spots grouped in rosettes. Its body is slender and muscular reaching a length of with a long tail and a shoulder height of . Males typically weigh , and females .
The leopard was first described in 1758, and several subspecies were proposed in the 19th and 20th centuries. Today, eight subspecies are recognised in its wide range in Africa and Asia. It initially evolved in Africa during the Early Pleistocene, before migrating into Eurasia around the Early-Middle Pleistocene transition. They were formerly present across Europe, but became extinct in the region at the end of the Late Pleistocene, around 11,000 years ago.
It is adapted to a variety of habitats ranging from rainforest to steppe, including arid and montane areas. It is an opportunistic predator, hunting mostly ungulates and primates. It relies on its spotted pattern for camouflage as it stalks and ambushes its prey, which it sometimes drags up a tree. It is a solitary animal outside the mating season and when raising cubs. Females usually give birth to a litter of 2–4 cubs once in 15–24 months. Both male and female leopards typically reach sexual maturity at the age 2–2.5 years.
It is listed as Vulnerable on the IUCN Red List because leopard populations are threatened by habitat loss and fragmentation, and are declining in large parts of the global range. Leopards have had cultural roles in Ancient Greece, West Africa and modern Western culture. Leopard skins have been popular in fashion.
