(Wired Science)  Animals’ Most Amazing Acoustic Feats
Toadfish (audio samples of hoots and grunt at link)
Some of the fastest-twitching muscles in the world reside in the two-chambered swim bladder of toadfish.
The frumpy-looking creature uses the muscles to vibrate their swim bladders, producing grunts and hoots. Some species’ territorial and mating calls are so loud in water (129 decibels) that they can be heard on land.
"A few decades ago, people near San Francisco Bay thought they heard a Soviet submarine attack underway, and they called the police," Patek said. "It turned out toadfish were making the sounds."
The strange calls also contain an extra layer of complex information, perhaps allowing for richer communication than was thought possible in the fish.
