Fish have 'talked' for 155 million years, and now you can hear their 'voices'

[Still Waters]

All manner of croaks, chirps, and deep trombone moans permeate Earth's waters, just like the cacophony of sounds that fill its forest air. For example, reefs are surprisingly noisy places, and many of the noisemakers are fish.

"We've known for a long time that some fish make sounds, but fish sounds were always perceived as rare oddities,'' said Cornell University ecologist Aaron Rice.

It was likely assumed fish relied primarily on other means of communication, from color signals and body language to electricity. But recent discoveries have demonstrated fish even have dawn and dusk choruses, just like birds.
