Discover the surprising similarities humans share with whales. Join Steve on an underwater expedition to learn about singing humpbacks, matriarchal sperm whales, and playful dolphins, and see how our early fear of whales eventually turned to wonder.

Confront Earth’s largest predators as Steve reveals the impressive hunting methods of orcas, blue whales, and boto dolphins. Watch them combine sound, strategy, and teamwork to catch their prey, then see how their clever strategies put them at risk.

Travel to places where migratory whales feed, breed, and raise their young despite imminent danger. Swim thousands of miles for a once-in-a-lifetime encounter with a southern right whale that’s about to give birth, then meet a curious humpback calf.

Examine human behavioural changes that can help save the whales. Venture to ocean hot spots to study dolphin communication, find out how Norwegian orcas train their young to hunt, and then board a unique research yacht that eavesdrops on cetaceans.
