The dolphin's voice.
Human ears cant hear it.
The ultrasound produce by dolphin will reflect back to them to comfirm the location of the object around them.
Also using by this kind of sound.
So, it can talk with other dolphin that are far away.
Wouldnt it be great if human could be like this too,
And talk to people that far away from us?
