The adult male, easily recognizable by his large mane, shows an average mass which can vary according to the geographical areas where he is found, ranging from 180 kg for the Kruger lions to 230 kg for the Transvaal lions. Some very rare specimens can exceptionally exceed 250 kg. An adult male eats 7 kg of meat each day against 5 kg in the female. The lion is a gregarious animal, that is to say, he lives in large family groups, unlike other felines. Its life expectancy, in the wild, is between 7 and 12 years for the male and 14 to 20 years for the female, but it frequently exceeds 30 years in captivity.
