Channel protein converts vibrations to electrical signal
...pond to sound, but also amplify the vibrations for quiet sounds as much as 100-fold. One hypothesis for how they do this, first proposed by James Hudspeth, is that after the transduction channels open with each cycle of sound, they quickly snap shut, and the force of this snapping can push the cilia bundle...To save dolphin's dorsal fin experts combine medical technology and teamwork
