Photographer Brian Skerry teamed up with James Cameron on the new series, "Secrets of the Whales," premiering Earth Day April 22 on Disney+.

Raised in Massachusetts, Skerry always wanted to be an ocean explorer and started doing underwater photography more than two decades ago.

"I fell in love with the sea as a child," he said on "Salon Talks." "I saw this place as a realm that I wanted to explore, what was lying beneath those dark waves out there on the ocean."

Watch the full episode above to hear about what new discoveries Skerry has made from studying whales and what he thinks humans can learn from them.
