Beluga families travel hundreds of miles each summer to spend time in their “summer playground.” Beluga whales are highly social and have complex cultures 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 Secrets of the Whales goes on sale April 6 and is available for preorder now.
