In contrast to what one may think when they look over the silent, unending horizon of the ocean, the seas are actually a vibrant auditory space. Scientists and our military submarines have experienced a wide range of noises from whale songs to volcanic eruptions. But there’s one sound that sticks out above all others – it is a particular whale song – from one animal whose songs always goes unanswered. Its calls are higher and shorter than any other, and it travels along a unique migration route. It’s as if this whale has his own language. Scientists have dubbed this creature “52 Hertz” and have been tracking it for over 20 years. No one has ever seen it though, provoking theories that this could represent a new species or a rare hybrid. Luckily for our ears, NOAA has recorded its calls.
