They have an excellent memory and they are also equivalent to excellent hearing! Elephants are able to hear infrasound, these sounds inaudible to the human ear because their frequency is less than 20 hertz. Thanks to this ability, elephants distinguish seismic waves that take place 30 kilometers away. A hearing capacity that allows them in particular to avoid certain natural disasters. They also hear the rustling of clouds, a key indicator that decides the direction of their migrations by telling them where the rain will fall. Photo credit: Valentin Pacaut / The Explorers
