Craig McClain is the Assistant Director of Science for the National Evolutionary Synthesis Center, a National Science Foundation supported initiative. He has conducted deep-sea research for 20 years and published over 50 papers in the area. He has participated in and led dozens of oceanographic expeditions taken him to the Antarctic and the most remote regions of the Pacific and Atlantic. Craig’s research focuses on how energy drives the biology of marine invertebrates from individuals to ecosystems, specifically, seeking to uncover how organisms are adapted to different levels of carbon availability, i.e. food, and how this determines the kinds and number of species in different parts of the oceans. Craig’s research has been featured on National Public Radio, Discovery Channel, Fox News, National Geographic and ABC News. In addition to his scientific research, Craig also advocates the need for scientists to connect with the public and is the founder and chief editor of the acclaimed Deep-Sea News (, a popular ocean-themed blog that has won numerous awards. His writing has been featured in Cosmos, Science Illustrated, American Scientist, Wired, Mental Floss, and the Open Lab: The Best Science Writing on the Web. His forthcoming book, Science of the South (, connects cultural icons of South such as pecan pie with the science behind them.

  1. Great video, octopus got distracted by the diver and paid the price, too bad it wasn’t a much bigger cuttle that ate the diver instead. Poor octo never stood a chance.

    Seriously though it is also interesting to see the small octo shoot that spanner across the structure like that when it was done checking it out. Then at :26 you knew it was all over for the octopus since the cuttle had the classic hunting posture just prior to striking. I’m just surprised the octopus was so entirely distracted by the tools and diver that it didn’t catch that it was being stalked by a cuttlefish only what, 1-2 inches away? Wonderful creatures cuttlefish!!!

  2. Hard to tell, but seems like the cuttlefish was mimicking the floating debris seen elsewhere in the video.
