Elephants live in family groups led by the oldest female, called the matriarch. She remembers where the water holes are in dry years, which routes are safe, and which other families are friendly. The family follows her wisdom. Young elephants stay close to their mothers and aunties for years.
An elephant's trunk is one of the most amazing tools in nature. It has around 40,000 muscles in it. Your whole body only has about 600. Elephants use their trunks like a hand to pick up a single blade of grass, like a hose to spray themselves with water, and like a snorkel to swim through deep rivers.
Tanzania has a special kind of elephant friendship: many elephants migrate between Tanzania's parks and Kenya's parks, walking right past Mount Kilimanjaro on the way. The animals do not understand borders. Park rangers from both countries work together to keep them safe.
Elephants 'talk' to each other in deep rumbles. The sound is so low that humans cannot hear it, but it travels through the ground for kilometres. A family on one side of a park can call to a family far away. They also greet each other with happy trumpets and gentle touches of their trunks.
