Photo by BrianSkerry / Secrets of the Whales / A newborn baby beluga whale swims in front of his mom in the shallow coastal waters in the Canadian high Arctic.

Beluga whales are highly social, and have complex dialects and ancestral traditions. 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 will also be featured in the May issue of National Geographic magazine, the Ocean Issue, available online on April 15.
