Lion

Lion
The lion (Panthera leo) is one of the four big cats in the genus Panthera, and a member of the family Felidae. With some males exceeding 250 kg (550 lb) in weight, it is the second-largest living cat after the tiger. 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. They typically inhabit savanna and grassland, although they may take to bush and forest. Lions are unusually social compared to other cats.

A pride of lions consists of related females and offspring and a small number of adult males. Groups of female lions typically hunt together, preying mostly on large ungulates. Lions are apex and keystone predators, although they scavenge as opportunity allows. Highly distinctive, the male lion is easily recognised by its mane, and its face is one of the most widely recognised animal symbols in human culture. Depictions have existed from the Upper Paleolithic period, with carvings and paintings from the Lascaux and Chauvet Caves, through virtually all ancient and medieval cultures where they once occurred. It has been extensively depicted in sculptures, in paintings, on national flags, and in contemporary films and literature.

Traditionally, 12 recent subspecies of lion were recognised, distinguished by mane appearance, size, and distribution. Because these characteristics are very insignificant and show a high individual variability, most of these forms were probably not true subspecies, especially as they were often based upon zoo material of unknown origin that may have had "striking, but abnormal" morphological characteristics. Today, only eight subspecies are usually accepted, although one of these, the Cape lion, formerly described as Panthera leo melanochaita, probably is invalid. Even the remaining seven subspecies might be too many.


some sub-species are :

Asiatic Lion
- Panthera leo persica, known as the Asiatic lion or South Asian, Persian, or Indian lion.Genetic evidence suggests its ancestors split from the ancestors of sub-Saharan African lions between 203 and 74 thousand years ago.

Barbary Lion
- P. l. leo, known as the Barbary lion, originally ranged from Morocco to Egypt. It is extinct in the wild due to excessive hunting, as the last wild Barbary lion was killed in Morocco in 1922.This was one of the largest of the lion subspecies

- P. l. senegalensis, known as the West African lion, is found in western Africa, from Senegal to the Central African Republic.

African Lion
- P. l. azandica, known as the northeast Congo Lion, is found in the northeastern parts of the Congo

- P. l. nubica, known as the East African or Masai lion is found in East Africa, from Ethiopia and Kenya to Tanzania and Mozambique; a local population is known as the Tsavo lion.

- P. l. bleyenberghi, known as the southwest African or Katanga lion, is found in southwestern Africa, Namibia, Botswana, Angola, Katanga (Democratic Republic of the Congo), Zambia, and Zimbabwe.

- P. l. krugeri, known as the southeast African or Transvaal lion, is found in the Transvaal region of southeastern Africa, including Kruger National Park.

Cape Lion
- P. l. melanochaita, known as the Cape lion, became extinct in the wild around 1860. Results of mitochondrial DNA research do not support its status as a distinct subspecies. The Cape lion probably was only the southernmost population of the extant P. l. krugeri.
