Elephants live in family groups led by the oldest grandma, called the matriarch. She remembers where to find water in dry years, which routes are safest, and which other families are friends. Her memory is the family's map.
An elephant's trunk is the most amazing tool in nature. It has around 40,000 muscles in it (your whole body has about 600). They use it 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.
Elephants talk to each other in a sound so low that humans cannot hear it. The rumble travels through the ground for several kilometres, so a family on one side of a national park can call to another family far away. They also greet each other with trumpets and gentle touches of their trunks.
Baby elephants stay close to their mum and aunties for years. The whole family takes turns looking after them — feeding them, splashing them with mud to keep them cool, and standing over them when they sleep. Elephants are famously gentle with their babies.
