Photo by @BrianSkerry / Secrets of the Whales / An orca feeds on a stingray off coastal New Zealand. Orca here have figured out how to navigate shallow water to predate on the rays. A preference for certain prey and creating feeding strategies to target them is an example of the whales' unique culture.

Disney+ original series Secrets of the Whales, from @NatGeo , is streaming this Earth Day, April 22, on @DisneyPlus . In addition, my book of the same name is on sale now wherever books are sold. My work on whales is also featured in the May issue of National Geographic magazine, the Ocean Issue, available online now. Learn more about all three at Nat Geo's Planet Possible hub, our newest initiative, which aims to inform, inspire and enable consumers to live more lightly on the planet: (link in bio).
