The lion is one of the four big cats with some males exceeding 250 kg (550 lb) in weight, It is the second-largest living cat after the tiger. Wild lions currently exist in sub-Saharan Africa and in Asia (where an endangered remnant population resides in Gir Forest National Park in India) while other types of lions have disappeared from North Africa and Southwest Asia They were found in most of Africa, across Eurasia from western Europe to India, and in the Americas from the Yukon to Peru.The lion is a vulnerable species, having seen a major population decline of 30–50% over the past two decades in its African range.Lion populations are untenable outside designated reserves and national parks. Although the cause of the decline is not fully understood, habitat loss and conflicts with humans are currently the greatest causes of concern. Within Africa, the West African lion population is particularly endangered.
Lions live for 10–14 years in the wild, while in captivity they can live longer than 20 years. In the wild, males seldom live longer than 10 years, as injuries sustained from continual fighting with rival males greatly reduce their longevity.
