Orcas, also called killer whales, number fewer than 100,000 worldwide, and learning more about them is a global endeavor for Jean-Michel Cousteau and his team of explorers, who travel to both the northern and southern hemispheres as they seek out killer whales in the Atlantic and Pacific oceans.

“What we’re trying to do is to make the connection between humans and nature, comparing humans and orcas,” stated Jean-Michel Cousteau. “They are the dominant species in the ocean. We are the dominant species on land and we all depend on the same thing.”
