Elephant, a very large animal with a long flexible nose to pick up things, live in layered societies. The basic family unit is formed of small groups of adult females, who are related to each other, and their young of both sexes. The females remain in their families for life. They’re highly social, but male elephants leave their families at about 14 years of age. They travel alone or gather round in small, loose groups with other males, occasionally joining a family on a temporary basis.
When males are ready to mate, they wander widely, searching for receptive females.
The family unit, on the other hand, often contains three generations, and it can remain stable for decades, or even centuries. Then each family associates with between one and five other families, probably consisting of their more distant relatives. Scientists call these groups of families"
