What Does the Sperm Whale Say? (Hint: It's Deep)

In May I went up to Saratoga with folks from Biomimicry San Francisco, Biomimicry Bay Area, and Coastal Redwood Biomimicry to hear James Nesbitt, author of Deep, speak about the human biology of free-diving (exciting stuff for this longtime Aquatic Ape aficionado), and learning how to talk to sperm whale in their own language. Two of the biggest superorganism species talking to one another??? Amazing!
