Sky has announced its brand new, ground-breaking nature series - Secret World of Sound with David Attenborough - will launch on Sunday 25 February on Sky Nature, as well as streaming service NOW.

Sky also unveiled the series trailer providing viewers a first look at this unique, three-part series, which explores how animals use sound to communicate, thrive and survive in the natural world.

Incredible footage captured throughout the documentary series will give viewers an intimate look at how baby caiman communicates with each other from within the egg, how lions and hyaenas battle in the dark using sound, how a strange fish baffled residents with its eerie hum, and how some birds have mastered the art of mimicry to remarkable effect. Packed with insight and new scientific discoveries, Secret World of Sound with David Attenborough will transport viewers into the natural world for an unforgettable experience full of wonder.

Filmed in 4K ultra-high definition, each episode of the series will feature in-depth stories of eight animals, followed by five-minutes of Behind-The-Scenes footage. Unveiling the very latest in audio technology, the series uses specially adapted cameras and laser vibrometers, which allows humans to truly eavesdrop on the animal world for the first time and discover new stories and information that have been hidden until now.

The series incorporates microphones so tiny, they fit on your fingertip, and so precise they can detect the noise of a baby caiman calling from inside the egg. With 360-Dolby Atmos Sound, viewers will experience the breath-taking sounds of the natural world as never heard before.
