沙漠动物-足智多谋的大象 Hints: African kilos the Nara bumper
African elephants are so resourceful, they can survive even here in the heart of the desert.
Elephants have remarkable powers of memory. Though this desert is more than two million square kilometers in size, 100 or so elephants it supports know precisely where to find enough to eat and drink. It takes a lot of food, up to 300 kilos a day to feed the world's largest land animal. And all of that from a desert.
But there's one plant here, the Nara, whose roots draw water from deep underground. Each year it produces a bumper crop of melons. Elephants just love them.
