Dolphins Call Each Other by Name | Amazing Dolphin Facts Documentary

Did you know dolphins have their own names? In this calm wildlife documentary, we dive beneath the waves to discover the surprising science of dolphins: signature whistles that work like names, echolocation that lets them "see" with sound, sleeping with half the brain awake, clever team hunting, and the long bond between mothers and calves.

We also meet the orca, the largest member of the dolphin family, the pink Amazon river dolphin, and the Māui dolphin, one of the rarest dolphins on Earth. Then we look at how we can help protect dolphins in the wild.
