Elephants

Elephants are the largest land creatures on the planet. A large African bush elephant bull can weigh between 11.5 and 12.25 tons, whereas a smaller African forest elephant can weigh up to 6 tons. The Asian elephant is roughly 8 tons in weight. Elephants live in groups of adult females and calves, with males leaving when they reach puberty. Elephant herds in Africa are commanded by a matriarch, but Asian elephant herds are less hierarchical. Asian elephants, unlike African elephants, can be domesticated and put to work. Elephants in Africa and Asia are both threatened.

The elephant is also one of the world's most intelligent creatures. It is one of the few creatures that are capable of self-awareness and recognition. It appears to employ equipment such as a fly swatter. It also has a strong ability to learn and recall information. Scientists are still debating whether elephants mourn their dead, but they do appear to have an emotional life on the inside.
