The lion, a large cat species native to Africa and India, is known for its muscular build, short rounded head, and the male's prominent mane. Lions are social animals, living in prides composed of a few adult males, related females, and cubs. Female lions primarily hunt, targeting medium to large ungulates, establishing the lion as an apex and keystone predator. While lions may scavenge or, in rare cases, attack humans, they don't actively seek humans as prey.
