Video: The Elephant Nature Park
Elephants have matriarchal societies, meaning a grandmother, her daughters, and their young form a herd. Herds can be as large as twenty, although most are twelve or less.
The young are cared for by the entire herd, as you can see in this video.
When the grandmother dies, the eldest daughter becomes the head matriarch.
One of the reasons I admire elephants so much is their devotion to the family unit. They form tight bonds and clearly love each other. This is also a reason why hunting and poaching elephants is so tragic – it affects the entire herd.
