Roosters Have Special Ears So They Don’t Crow Themselves To Deaf

"Loud sounds (above 120 decibels) can cause permanent hearing losses because the intense air pressure waves can damage and even kill the cells that translate sounds into neurological signals. At more than 130 decibels, it takes less than a second to inflict lasting damage. So you’d think that roosters crowing every day would slowly squawk themselves to total deafness. Since they don’t, scientists figured they must have some way of protecting their ears when they crow."
"If one cock-a-doodled right in your ear, the sound is even louder—over 140 decibels. Sounds that loud can cause damage in less than a second, and are just shy of shattering your eardrum."

Starting around the 5 minute mark the video becomes quite worrisome and horrifying off the coast of Australia.

An interesting flashing effect using silica nano spheres is used by a clam.
The electric clam is at the 10:45 minute mark.
