Sharks Can Hear The Low-Frequency Sounds Of Dying Fish

Sharks don't have ears on the outside of their bodies, but they do hear through an internal sound system. There is a tiny hole on each side of the top of a shark's head that leads to ducts filled with fluids that carry sound waves. These holes are called endolymphatic pores.

A shark's sense of hearing is, in fact, its strongest sense. It can hear sounds up to a kilometer away or more.

Sharks don't talk, of course, but scientists believe that sharks may be able to communicate with each other by emitting and hearing very low-frequency sounds. And sharks hear things like changes in the water currents, which helps them stay balanced in the water and adjust their positions.

Their hearing system makes them very good at picking up the low-frequency sounds that travel through the ocean. One of the sounds sharks hear is called the Yummy Hum. Too low for humans to hear, the Yummy Hum is a sound that dying fish emit and it lets sharks know there's something good to eat in the area.
