Extreme suction helps elephants suck up water quickly, and to hold water and food in their trunks. Extreme suction enables elephants to inhale water at speeds nearly 30 times faster than humans exhale air during a sneeze.
New Scientist magazine, on 2 June 2021, announced recent research results on the effectiveness of elephants using extreme suction. Elephants use their trunks, which weigh more than 100 kilograms (220 pounds), in a variety of ways: to forage through vegetation for food, to drink, and even as a snorkel when wading through deep water.
To better understand the trunk in action, scientist Andrew Schulz at the Georgia Institute of Technology in America, and his colleagues, filmed a 34-year-old female African Savannah Elephant (Loxodonta africana) while she completed a series of tests at a zoo in Atlanta.Continue reading “RESEARCH: Elephant trunks use extreme suction to suck up water quickly: faster than a human sneeze”
