Trunk power! A 34-year-old African elephant at Zoo Atlanta, in Georgia, has just taught mechanical engineers, at the Georgia Institute of Technology, a thing or two about how to move water. For one thing, she showed that her trunk doesn’t operate as a simple straw. To suck up water, she dilates that trunk expands it. Elephants are the only living land animals with a long, boneless trunk. But precisely how elephants use those muscular trunks for feeding was always been a bit of a mystery. Ultrasound imaging showed that the available volume of each nostril could balloon as it snorted in liquid. Based on the amount and rate of water snuffed up by the elephant, Schultz’s team estimates that airflow through her narrow nostrils can at times exceed 150 metres per second (335 miles per hour). That’s more than 30 times as fast as a human sneezes.
