Lions are family animals and truly social in their own communities.They usually live in groups of 15 or more animals called prides.Prides can be as small as 3 or as big as 40 animals.In a pride, lions hunt food, raise little lions, and defend their territory(领地) together.
In prides the females do most of the hunting and care for little lions.Usually all the females in the pride are related—mothers, daughters, grandmothers, and sisters.
Each pride generally will have no more than two adult males.While the females usually live with the pride for life, the males often stay for only two to four years.After that they go off on their own or are evicted(逐出) by other males who take over the pride.
When a new male becomes part of the pride it is not unusual for him to kill all the little lions, making sure that all future little lions will have his genes.
The main job of males in the pride is defending the pride's territory.A male's loud roar(吼叫), usually heard after sunset, can carry for as far as eight kilometers.The roar warns off intruders(入侵者) and helps round up small members of the pride.
Hunting generally is done in the dark by the females.They often hunt in groups of two or three, using teamwork to surround, and kill other animals.Females aren't the most successful of hunters, because they usually score only one kill out of several tries.After the kill the males usually eat first, females next and the little lions get what's left.Males and females defend against any outside lions that attempt to join their pride.
