How Can a Sperm Whale Hunt in Complete Darkness Thousands of Feet Below the Ocean?

Thousands of feet beneath the ocean surface, sunlight disappears. Yet sperm whales descend into this darkness to hunt. With vision severely limited in the deep sea, these enormous predators rely heavily on sound. They produce powerful clicks and listen for returning echoes, using echolocation to investigate their surroundings and track prey in a world they cannot simply see. But finding prey is only the beginning. A sperm whale must dive to extraordinary depths, manage a limited oxygen supply, locate moving prey in darkness, pursue it, and eventually return to the surface. In this WildDecoded documentary, we follow the sperm whale from the surface into the deep ocean and uncover how echolocation transforms sound into a remarkable sensory advantage where sunlight cannot reach. In the deep sea, darkness doesn’t end the hunt. Sound becomes another way of sensing the world.
