Extreme suction helps elephants hold water and food in their trunks, allowing them to inhale at speeds nearly 30 times the rate at which we exhale air when we sneeze.

Elephants use their trunks, which weigh more than 100 kilograms, in a variety of ways: to forage through vegetation for food, to drink and even as a snorkel when wading through deep water.
