Stunning Footage of Sperm Whales Attempting to Communicate With Freedivers Using Clicking Noises

In 2014 James Nestor, freediver and author of the book DEEP: Freediving, Renegade Science, and What the Ocean Tells Us about Ourselves, gave a fascinating talk entitled “Humanity and the Deep Ocean” at The Interval at Long Now in San Francisco.

To illustrate his the subject of his lecture, Nestor shared some absolutely stunning footage of several freedivers engaging with enormous but welcoming sperm whales who tried to communicate with their very loud clicking language that whales use amongst themselves.
