"Thank You Ocean" Campaign: Jean-Michel Cousteau Talks about his Love and Concern for Orca

They are the most widely distributed marine mammal in the world. Their realm extends from the Arctic to the Antarctic. Orcas, also called killer whales, number fewer than 100,000 worldwide, and learning more about them was a global endeavor for Jean-Michel Cousteau and his team of explorers, who traveled to both the northern and southern hemispheres as they filmed killer whales in the Atlantic and Pacific oceans for the PBS special, "Call of the Killer Whale."

Now years later, the 'Thank You Ocean' campaign features Jean-Michel in this week's ocean report where Jean-Michel shares his knowledge and passion for these socially complex and intelligent animals.
