The series features never-before-seen footage, and unveils new science and technology to spotlight the whales as they teach their young, adapt to survive and even mourn for the loss of loved ones. Yes, it’s a weepy one!

How to watch Secrets of the Whales

All four episodes of the National Geographic series will be available on Disney Plus from Thursday 22^ndApril.

What is Secrets of the Whales about?

Secrets of the Whales follows groups of whales over three years, revealing their unique social structures and communication skills in underwater footage.

The first episode focuses on orcas and how they have adapted to remain at the top of the food chain (Patagonia’s whales catch sea lions on the beach while New Zealand orcas survive on stingrays, for example) and follows orca mothers as they teach their young how to hunt. Later episodes focus on humpbacks, which communicate using complex songs, belugas and narwhals in the freezing oceans of the north, and the majestic ocean giants known as sperm whales.

The series has some never-before-seen moments, too, including evidence that suggest belugas give themselves names so they can keep track of each other, and the first cross-species adoption ever recorded as a beluga pod adopts a narwhal. Cutest of all has to be the footage of a sperm whale mother nursing its calf – a moment that has never been recorded on video before.
