The Sperm Whale Mother and Calf: Deep Diver and Patient Waiter

In The Sperm Whale Mother and Calf: Deep Diver and Patient Waiter, narrator Sir David Attenborough observes a sperm whale and her calf, resting, communicating, and feeding. The calf won’t be able to dive deep enough to hunt for squid for the first six years of life, but the mother dives and hunts and returns with a store of milk for the waiting calf. This video is excerpted from BBC’s Blue Planet II, a natural history series that explores the world's oceans, the animals that live in them, and the threats they face, using modern filming techniques and equipment to capture previously unseen areas of the ocean.
