Elephants flap their large ears to help release excess body heat through a dense network of blood vessels. As blood circulates close to the ear’s thin skin, heat is transferred to the surrounding air. Flapping increases airflow, speeding up the cooling process much like a natural fan. This mechanism is especially important because elephants have massive bodies that retain heat easily. Without efficient sweat glands, ear flapping becomes a vital strategy for maintaining a stable body temperature.
