How an Elephant Breathes Underwater
An elephant’s trunk is both a nose and a remarkably flexible breathing tube. Its two nostrils run through the trunk and open at the tip, so an elephant can lower most of its head and body beneath the surface while holding the tip in the air. Air travels down the trunk to the lungs, much as it would through a snorkel.
The Trunk Must Stay Clear
The arrangement works only while the trunk’s tip remains above water. If it goes under, the elephant cannot draw air through it. The animal can raise or reposition the trunk as it moves, keeping the openings clear while wading or swimming.
This is not a separate breathing adaptation: the trunk is the elephant’s ordinary airway, extended far beyond its face. Its length gives the animal room to breathe even when its body is submerged, but it does not let the elephant breathe underwater. The tip still has to reach open air.
A Built-In Breathing Tube
Because the trunk is also used for smelling, grasping, and drinking, it can be directed with fine control. In water, that flexibility becomes useful in a different way: the elephant can keep its airway at the surface while the rest of it moves through the water. The vivid image of an elephant “snorkeling” is therefore accurate, with one practical condition—the breathing end must stay out of the water.
