Elephants are one of the world's most iconic animals.
There are two main elephant species – African and Asian.
African elephants are Earth's largest land mammals, found across the African continent.
The Asian elephant is smaller than its African cousin, and can be found across Asia, from southern India to Borneo.
In the wild both species of elephant cover vast distances, foraging for food such as grass, roots and bark.
An elephant can eat 136kg of food a day
Female elephants, or cows, live in herds with their young, led by one matriarch – the oldest female of the group. But adult males, or bulls, roam alone.
An elephant's trunk is a complex tool used for breathing, smelling, communication, drinking, and feeding.

Tusks are used as a weapon against predators and in battle with other elephants.
Males use them to attract a mate.
And tusks are also useful for digging up food and stripping bark from trees.
Elephants have large ears, but these are not only for hearing; they radiate heat to keep the elephant cool.
And amazingly, elephants also hear with their feet, by picking up vibrations made by other elephants through the ground.
Unfortunately, elephants are illegally hunted for their tusks, and particularly in Asia are suffering from habitat loss as more and more land is cleared for agriculture.
But huge conservation efforts are being made to protect these giants and ensure their survival.
