ACKNOWLEDGMENTS

We are most grateful to Ivy Press for initiating this endeavor. In the early phases we appreciated the professional guidance and patience of Commissioning Editor Kate Shanahan and Editorial Director Tom Kitch. University of Chicago Press Editorial Director Christie Henry was very supportive of this effort and was instrumental in orchestrating the joint publication. As the actual writing and photograph collection proceeded over a 2-year period, we worked most closely with Ivy’s Project Editor Joanna Bentley. Her enormous experience combined with her gentle and effective nudging to meet multiple deadlines are deeply appreciated.

Roger thanks many dive partners and lab colleagues over the years who enabled a great deal of discovery of cephalopod biology. Mike appreciates his wife Susan and her decades of tolerance for his long absences at sea that were necessary to learn some of the information on deep-sea cephalopods presented here. Louise is hugely grateful for the support of Felix and Poppy, who let Mum write when she should probably have been playing, and Mark, who made sure nobody starved.
