When swimming or wading in deep water, elephants often use their trunks as natural snorkels, extending the trunk above the surface to breathe while the rest of the body is submerged, allowing them to cross rivers and swim for extended distances.
How they use the trunk
An elephant’s trunk is a versatile, elongated nose and upper lip that can be raised vertically to keep the nostrils clear of water. During swimming, the animal’s large lungs and buoyant body help it stay afloat while the trunk acts as a breathing tube, enabling continuous respiration even when the head and shoulders are underwater.
Swimming behavior
Elephants are strong swimmers and can paddle for long distances using slow, powerful limb strokes. They alternate between walking along shallow beds and free swimming; when the water deepens, they switch to swimming and rely on the trunk to reach above the surface for air, sometimes moving in family groups that encourage younger or weaker animals.
Anatomical adaptations
The trunk’s length, flexibility and muscular control make it an effective snorkel, while the animal’s lungs and body fat distribution increase buoyancy. Elephants can also seal the trunk when diving briefly, using it to blow out water and clear the airway before taking the next breath.
Ecological significance
Using trunks as snorkels allows elephants to cross wide rivers during seasonal migrations, access distant feeding grounds and escape threats. River crossings are important for gene flow between populations and for accessing seasonal resources, although they carry risks from currents and predators in some regions.
