How big are an elephant's ears?

African Elephant's ears are 42 in. (107 cm) in diameter. Indian

elephants have smaller ears.

They keep the elephant cool. Elephants' ears are thin-skinned

and rich in blood vessels. The ears of some African elephants are

nearly 2 meters long and almost as wide, much bigger than those of

Indian elephants. When an African elephant waves its ear flaps, it

can lower the temperature of the blood flowing within them by as

much as 5 degrees Celcius. Indian elephants are essentially

creatures of shady forests. They don't have to endure the high

temperatures that African elephants encounter on their sunburnt

grasslands, so they do not need such large ears.
