A BBC Team has captured a herd of elephants' clever trunk trick in the Kalahari. Instead of wading into the water - as is typical for elephants- this herd has learned amazing control. When faced with limited water in a stagnant pond they have learned to restrain themselves, enter the water gingerly and use their trunks to skim the surface for the freshest water.

The video was captured by Mike Holding for the show "Nature's Great Events: The Great Flood", which follows the annual flooding of Botswana's Okavango Delta, where, for a limited time, the surrounding desert is transformed into a lush wetland.
