I Googled the above and didn't find much but did find this
"When the flash went off the fish convulsed and shot away in panic like it had been fired from a rail gun right smack into a limestone boulder. I will never forget the sound of pounds of flesh and bone hitting solid rock at that velocity. A lot of you have had the experience of feeling sound underwater, particularly lower frequencies. I felt that fish's head hit the rock and it resonated in my own head just a couple of feet away. The force and weight of the impact made a sound that still makes me wince."
Are there any studies? I've seen some comments about concerns around sea life that does not have eyelids.
