One of Africa's Big Five, the lion is a carnivore (meat eater) and a hunter. It uses its powerful forelegs to grab or slap down large prey that would otherwise outrun it. Male lions are 20 to 35% larger than the females and 50% heavier. The male's chief role is to protect the pride's territory and females from other males. Size is therefore an advantage though it increases the male's need for food. Only males grow a mane. It causes him to look bigger without increasing his weight or need for food. It also protects him from bites and scratches should he have to fight another male.
