Have you ever heard a haddock knock? What about a cusk eel’s chatter?

Sound travels four-and-a-half times faster through water than air and can be heard across huge distances. It’s how whales are able to communicate hundreds of kilometres apart. Yet, for all its wonder, much of the underwater acoustic world remains a mystery to scientists.

Although human ears can’t detect most marine sounds, the invention of hydrophones – microphones designed to capture underwater audio – is helping scientists begin to unravel this hidden world.

So how does sound move through water? And how do underwater creatures perceive and use sound? Amorina Kingdon’s new book ‘Sing Like Fish’ explores these questions, revealing how marine life depends on ingenious uses of sound to communicate, navigate, and thrive.

In this episode, Kingdon and host Christie Taylor explore the fascinating ways fish and other marine animals produce sound, the physics of underwater ears, and how humans are impacting critical underwater soundscapes. Plus, samples of some of the most captivating underwater sounds she’s encountered in her research.
