Did Ja Know?

Male oyster toadfish emit foghorn-like whistles to attract females during spawning. The decibel level approximates that of a car horn at 5 meters; so loud that the whistles detonated acoustic mines in the ocean during World War II, forcing the U.S. Navy to withdraw the mines from the U.S. seaboard. You can hear the sound at: www.wikipedia.org/wiki/Oyster_toadfish.
