The leopard is one of the "big five" together with elephant, lion, rhino, and the african buffalo. It is the fourth largest of the "big cats" in the world with the jaguar, lion and tiger being larger and the fifth largest of all cats with Pumas being slightly larger. Leopards range in size from one to just over two metres (6.5 ft) long, and generally weigh between 30 and 70 kg (65–155 lb). Some males may grow over 90 kg (200 lb). Females are typically around two-thirds the size of males. For its size, the leopard is the most powerful feline in the world next to the jaguar. Leopards tend to be the apex predator in areas where bigger competitors do not occur, especially lions and tigers. This explains why the leopards in areas such as the African rainforests or Sri Lanka are larger than leopards elsewhere.
Most leopards are light tan or fawn with black rosettes, but their coat color is highly variable. There are smaller rosettes and spots on the head.
Leopards are truly opportunistic hunters. They will eat just about anything. Their diet consists of mostly monkeys, rodents, reptiles, amphibians, birds, fish, wild pigs, and ungulates. Their prey ranges in size from a snack of beetles to enormous adult common eland, which can weigh over a ton. In Africa, mid-sized antelopes provide a majority of the leopard's prey, especially Thomson's gazelles and reedbucks. It stalks its prey silently and at the last minute pounces on its prey and strangles its throat with a quick bite. When it kills animals such as gazelle, it carries them up into the trees to eat it. Leopards are capable of carrying animals up to twice their own weight into the trees.
Although most leopards will tend to avoid humans, people are occasionally targeted as prey. Most healthy leopards prefer wild prey to humans, but cats who are injured, sickly or struggling with a shortage of regular prey often turning to hunting people and may become habituated to it. In the most extreme cases, both in India, a leopard dubbed "the Leopard of Rudraprayag" is claimed to have killed over 125 people and the infamous leopardess called "Panar Leopard" killed over 400 after being injured by a poacher and thus being made unable to hunt normal prey. The "Leopard of Rudraprayag" and the "Panar Leopard" were both killed by the legendary hunter Jim Corbett.
