As a Senior Scientist at the Marine Biological Laboratory in Woods Hole, Massachusetts, Roger Hanlon delves into the undersea world of chameleon-like, color-changing marine animals — and the practical applications that will emerge when we crack their secrets.

Why you should listen

According to Roger Hanlon, "The diversity and sophistication of marine animals fascinates me, and my cornerstone passion is animal behavior. I particularly enjoy diving in different ocean habitats and studying animals that change color and pattern -- especially octopus, cuttlefish and squid, but also various coral reef fishes.

"I stumbled on to this journey while casually diving in Panama as a college junior and, decades later, I am still striving to figure out how these magnificent animals do what they do -- and why they do it. I am keenly interested in the 'visual ecology' of rapid adaptive coloration used for both camouflage and communication."
