Dive into the fantastic world of cephalopod camouflage in this video featuring MBL Senior Scientist Roger Hanlon. It's the first episode in a new ocean science series produced by Quartz (part of The Atlantic Monthly) for Facebook. The video was produced by Erik Olsen, who accompanied Hanlon on several dives. Olsen, formerly a video journalist for The New York Times, was a fellow in the MBL's Logan Science Journalism Program in 2013.
