The lion's roar is inaudible to most prey

The lion's roar—one of nature's fearsome sounds, audible from 5 miles away—represents an evolutionary puzzle: frequencies at which lions roar are largely inaudible to many primary prey. Lions roar primarily at 400-2000 Hz, with most intense energy around 500 Hz. However, main prey animals (zebras, wildebeest, antelopes) are most sensitive to 1-10 kHz ranges, making the roar only partially audible. This mismatch suggests the roar evolved for intra-species communication—conveying information about location, reproductive status, and territorial claims to other lions—rather than hunting. Male lions use roaring to advertise presence to females and challenge other males, serving as long-distance communication. To prey animals, the roar signals large predator presence rather than providing specific targeting information.
