A lively discussion on whether cuttlefish can count (and how to experimentally test that question) wrapped up the weekly talk series by The Cephalopod Group, which was birthed at the MBLthis summer. MBL10-20 octopus, squid, and cuttlefish researchers attended the talks each week, organized by��, Associate Director of the��at MBLand Associate Professor of Biology at Denison University.

“I am new to cephalopod research myself, so I was excited to work with the Grass Fellows and the many experts at MBLto learn more,” says Rhodes, noting that three of the 2018 Grass Fellows worked with cephalopods.

“What I liked best about the meetings was the diversity of knowledge and interests in the room,” Rhodes says. “We had people brand new to cephalopods, those who have spent a career studying them, and everything in between. We had experts in anatomy, physiology, behavior, development, ecology, animal husbandry, and genomics all come together to share and learn. All were welcome to contribute, present, and ask questions. And a lot of us were able to get help with our projects through the group - people gave advice, loaned a book, e-mailed a reference, offered to teach a technique or loan a reagent.”

Rhodes got an assist in launching the Cephalopod Group from MBLSenior Scientist��Roger Hanlon, who “offered strong encouragement early on and attended nearly every meeting.” Also enthusiastic were Bret Grasse, MBLManager of Cephalopod Operations, and Lisa Abbo, MBLVeterinarian and Scientist. “We immediately added other faculty, visiting researchers, Whitman scientists, students, and researchers from Woods Hole Oceanographic Institution,” Rhodes says.

A range of speakers and topics in cephalopod research contributed to group discussions. A partial list includes: genomics and RNA editing (, Stanford University/Grass Lab), chemosensation (Rhodes and Kaitlin Fouke, Denison University/Grass Lab), phylogenetics (Carrie Albertin, ��Ůֱ������), creating transgenics (, St. Mary’s College of Maryland/MBLWhitman Center), camouflage (, Columbia University/Grass Lab), imaging skin (, ��Ůֱ������), cognition (, University of Caen/University of Cambridge/Grass Lab), effects of ocean acidification (Woods Hole Oceanographic Institution), effects of anthropogenic sound (, WHOI), feeding and striking behavior (Andrea Fusco, Northeastern), and integer and fraction number sense (/National Tsing Hua University/Roger Hanlon collaborator).
