Close-up imagery showing barnacles covering sulphur structures on Kawio Barat volcano. Their tentacles, or ‘cirri,’ extended like blooming flowers, then folded back into the shell. The white fluff on the cirri are filaments of bacteria that grow in the passing vent water. The barnacles hold them out to improve growth then, apparently, withdraw to “lick their fingers.” High resolution (Credit: Image courtesy of INDEX 2010: "Indonesia-USA Deep-Sea Exploration of the Sangihe Talaud Region.")

Craig McClain is the Assistant Director of Science for the National Evolutionary Synthesis Center, created to facilitate research to address fundamental questions in evolutionary science. He has conducted deep-sea research for 11 years and published over 40 papers in the area. He has participated in dozens of expeditions taking him to the Antarctic and the most remote regions of the Pacific and Atlantic. Craig’s research focuses mainly on marine systems and particularly the biology of body size, biodiversity, and energy flow. He focuses often on deep-sea systems as a natural test of the consequences of energy limitation on biological systems. He is the author and chief editor of Deep-Sea News, a popular deep-sea themed blog, rated the number one ocean blog on the web and winner of numerous awards. Craig’s popular writing has been featured in Cosmos, Science Illustrated, American Scientist, Wired, Mental Floss, and the Open Lab: The Best Science Writing on the Web.
