The dolphin has the best hearing amongst us all. They hear 14 times better than humans, and also use echo-location with a range that is far greater than the bat, about 80kHz to an incredible 150kHz.
This information I read from a brochure about hearing aids..
besides, I heard that dolphins bring hope~like them.
