Elephants: Names, Memory, and Secret Messages

Elephants are intelligent mammals with complex social structures. They live in herds led by an older female called a matriarch. To survive in vast landscapes, they rely on advanced methods of communication and exceptional memory.

Individual Names and Calls

Recent research indicates that wild African elephants address one another using specific calls. These sounds function like names. When an elephant produces a low rumble intended for a specific individual, that individual responds, while others ignore it. These name-like calls allow members of a herd to coordinate movements and stay connected even when they cannot see each other in dense bush or tall grass.

Listening Through the Ground

Elephants communicate using sounds that are too low for humans to hear, known as infrasound. These low-frequency rumbles travel through the air, but they also travel through the ground as seismic vibrations. An elephant has special fatty pads in its feet that are sensitive to these vibrations. By pressing their feet and the tips of their trunks against the soil, they can detect stomping or calling from other herds miles away. This allows them to sense danger or locate mates long before they hear anything with their ears.

The Matriarch’s Memory

An elephant’s brain is the largest of any land animal, weighing about 11 pounds (5 kilograms). The temporal lobe, the area of the brain responsible for memory, is highly developed. This memory is critical for survival. The matriarch remembers the locations of water holes and food sources across hundreds of miles. During severe droughts, older matriarchs recall survival routes used decades earlier. They also remember specific individual elephants from other groups, distinguishing between friends and strangers to keep the herd safe.
