Elephant families are led by the oldest female, called the matriarch. She remembers where the water holes are, which routes are safe and which other families are friendly. The whole family - mothers, aunties, sisters, cousins, calves - travels together. Adult males usually leave the family and roam either alone or in small bachelor groups.
An elephant's trunk is one of the most amazing tools in nature. It has around 40,000 muscles in it. Your whole body has just 600. Elephants use their trunks to pick up a single blade of grass, to spray themselves with mud, to greet each other with gentle touches and to make low rumbling sounds to talk across kilometres.
Zimbabwean elephants often cross between countries. The same herd might walk from Hwange in Zimbabwe into Botswana, across into Namibia, and back again - all in one journey. To help protect them, five countries (Zimbabwe, Botswana, Namibia, Zambia and Angola) work together on a giant connected reserve called KAZA, the size of France.
Elephants can live to be 70 years old. Calves stay with their mothers for at least ten years - longer than most other animals. Mothers and aunties teach the young what to eat, how to find water and where to walk. Without that family learning, a young elephant would struggle to survive.
