About this video

Sperm whales dive deeper than submarines and hold their breath for over ninety minutes, yet science still cannot fully explain how they survive the crushing pressure without collapsing their lungs. This video follows one extraordinary animal through record-breaking dives, sonar clicks that stun prey in darkness, and matriarchal societies that pass down knowledge like living libraries.
