African lions live on savanna grasslands, while Asiatic lions, which are reduced to a single population in Gujarat, India, live in a mixture of dry savanna forest and very dry deciduous scrub forest. It is believed lions were common in Greece during classical antiquity.
Lions are members of the genus Panthera, which includes other big cats, such as the tiger, the leopard and the jaguar. As the second-largest cat in the world, a male lion can weigh 550 pounds or more. Lions display sexual dimorphism; males are larger than females and have manes. A male lion's mane is linked to his health and sexual attractiveness. Fuller, darker manes indicate a healthier animal.
