How elephants send messages through footsteps and hear through skulls

Through the ground, elephants send and receive vibrations, a unique way of communicating that surpasses traditional airborne sounds. Their anatomy, featuring sizable middle ear components and eardrums, allows for the efficient transfer of low-frequency signals to the cochlea. Intriguingly, they can also close their ear canals at will, amplifying their ability to perceive these low frequencies. This remarkable skill unveils the depths of their sophisticated communication systems.
