How do color-blind cephalopods -- octopus, squid and others -- achieve such a good color match when they camouflage? (in short: amazing, distributed brains). And what does it take to study these elusive animals in the wild? (a whole lot of patience). Marine scientist Roger Hanlon dives deeper into his research.Continue reading
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 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."
