LION Only male lions boast manes, the impressive fringe of long hair that encircles their heads. Males defend the pride's territory. They mark the area with urine, roar menacingly to warn intruders, and chase off animals that encroach on their turf. Female lions are the pride's primary hunters. They often work together to prey upon large mammals. After the hunt, the group effort often degenerates to squabbling over the sharing of the kill, with cubs at the bottom of the pecking order. Young lions do not help the pride hunt until they are about a year old. Lions will hunt alone if the opportunity presents itself, and they also steal kills from hyenas or wild dogs.
