This is a contribution of the past and present staff of the Pelagic Invertebrates Collection.  We also thank Alison Cawood and Connie Fey as well as UCSD undergraduate students Thomas Buno and Mei Hui "Leimmi" Zhang who conducted extensive photographic imaging and scanning for this project.  We express appreciation to the numerous photographers, authors, and publications who gave us permission to reproduce their work here.

We express particular thanks to the Beyster Family Foundation for the financial support that made it possible to initiate this project, to the National Science Foundation for support of the California Current Ecosystem LTER site, and to the Scripps Institution of Oceanography webgroup for their technical assistance.
