Lions are the only cats that live in groups, which are called prides—though there is one population of solitary lions. Prides are family units that may comprise anywhere from two to 40 lions—including up to to three or four males, a dozen or so females, and their young. All of a pride's lionesses are related, and female cubs typically stay with the group as they age. Young males eventually leave and establish their own prides by taking over a group headed by another male.

Males defend the pride's territory, marking the area with urine, roaring menacingly to warn intruders, and chasing off animals that encroach on their turf.

Female lions are the pride's primary hunters and leaders. They often work together to prey upon antelopes, zebras, wildebeest, and other large animals of the open grasslands. Many of these animals are faster than lions, so teamwork pays off. Female lions also raise their cubs communally.

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 to 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 hogs.
