African lions are sexually dimorphic (have two distinct gender forms). Males are larger and have a mane. Their fur is light tawny, with white on the belly and the inner side of the legs, while the back of their ears and their tail tip are black. The mane can be tawny to reddish-brown to black. Adult males usually have a dark mane on the head, neck, and shoulders, which offers protection to the neck during fights. Both sexes have a tuft of fur on the tip of the tail.
