African Field Notes: The African Elephant
The African Elephant is the heaviest, largest land mammal in the world. Some adults weigh more than 14,000 lbs & their brains are 3-4x the weight of the human brain.
Elephants have lots of blood vessels in their ears. They flap their ears and their blood pumps through, cooling and then circulates back to the rest of the body. This is important because elephants don’t sweat. If they get overheated and cannot find water, they can stick their trunk down into their own stomach to get a bit of water to spray over their back.
The elephant's trunk has approx 150,000 muscles, and its used as a nose, arm and hand. Babies don’t know how to use trunk when they are born, instead they drink with mouth. Sometimes they just wiggle their trunks or suck on them like a baby would on a thumb.
Family units are led by the oldest female, who is often 40 or 50 years old, while males visit only for mating. It takes almost two years got a baby elephant to gestate – the longest of all land mammals. When an elephant is about to give birth, other female elephants may act as a midwife and comfort the expectant mother.
They communicate using something called infrasonic sounds, which are very low noises that can be heard for miles. There have also been instances of mimicry – like an elephant mimicking the noises of a truck.
Elephants also communicate thru scent – giving off smells when ready to mate, when they’re sick or about to give birth but what is most interesting is how they show empathy for each other. Elephants are known to care for others in their family. They’ll often slow down or help physically support an ailing fellow, even bringing food if they cant for themselves.
Elephants grieve, sometimes for months – especially youngsters who lose their mothers. When an elephant dies, it is not just abandoned. The family unit stays with the corpse, sometimes for days. Then, after a while, one by one they touch the body and turn away. Sometimes they will even cover the body with brush and dirt. Elephants ignore the bones of other creatures, but if they come upon elephant bones, even years later, they will stroke them, and then sometimes scatter them.
