For many whales and dolphins, the world is shaped by sound; they hunt and navigate by listening for echoes. Navigating in this way requires super-sensitive hearing. And scientists have now found that, for some whales, this sense is adjustable. Researchers in Hawaii measured the hearing of a female false killer whale, and found that she could fine-tune her most crucial sense.

Sensors attached to suction cups on Kina’s body took measurements of her brain activity.
The whale would “turn down” her hearing when she anticipated a loud noise.
