But instead of using their mouths or noses to emit the sound, they use a fatty deposit in front of the blowhole or a melon. The melon helps focus the sound on delivering a more accurate image. The whale receives the vibration via another fatty organ in the middle ear, which transmits the signal to the brain.]]> 2023-03-06 20:25:11 UTC https://padlet.com/xjzhang01/o6ttiz5s2ylmju24/wish/2505771467 xjzhang01 https://padlet.com/xjzhang01/o6ttiz5s2ylmju24/wish/2507513768 The brain then makes out the size, shape, location, distance, speed, and even texture of the object(s) it senses.]]> 2023-03-07 20:26:27 UTC https://padlet.com/xjzhang01/o6ttiz5s2ylmju24/wish/2507513768 xjzhang01 https://padlet.com/xjzhang01/o6ttiz5s2ylmju24/wish/2507524728 Dreyfuss, John Henry.
