Although not well articulated in the early years, it became clear much later that these compounds formed the foundation of defense and communication. Decades later, Whittaker and Feeny’s classic 1971 paper, “Allelochemics: Chemical Interactions between Species,” provided an organizational foundation for describing the vari- ous functions of these adaptive chemical compounds. During the same period, and in stark contrast, knowledge of the chemistry of marine life was fundamentally non-existent. Early chemical studies by Richard Moore and Paul Scheuer in Hawaii focused on the fascinating pigments of the brightly colored echinoderms, while stud- ies of toxic edible marine species formed a major area of research in Japan. However, the natural functions of these elaborate metabolites remained unexplored for at least another decade. One of the first areas to be explored was the role of marine algal metabolites in structuring predator prey relationships. The unique chemical components of the seaweeds, many of which were produced by a revolutionary halogen-based biosyn- thesis, provided ample rationale to consider these compounds as providing an adap- tive role. Chemists, whose background was limited in ecology, began to agitate their ecologist colleagues to accept this reasonable hypothesis. As time passed, chemists openly interacted with young marine ecologists to emphasize how important this work could be in shaping marine ecology. A story comes to mind that demonstrates the level of understanding in the early 1970s. For several years, biological oceanographers had mapped the world’s oceans, measuring chlorophyll and relating their measurements to overall oceanic produc- tivity assuming the food chain transfer of phytoplankton nutrients into the higher trophic levels. They quantified their chlorophyll data to high resolution, never ques- tioning the validity of their assumptions. In the late 1970s, copepod feeding studies clearly showed that these herbivores carefully select phytoplankton, avoiding a large abundance of chemically rich and un-preferred prey. Alas, the very foundation of their work was now considered questionable if not completely useless. The roles of chemical feeding inhibitors had simply not been considered in assessing how the oceans function. In the mid-to-late 1970s, young marine ecologists took note of the potential of this new, developing field. The opisthobranchs were found to be specialists prey- ing on chemically defended plants and animals in order to use their defenses for their own. The hypothesis that the shell-less opisthobranch mollusks had, over evo- lutionary time, lost their shell provided great insight into the complexity of chemical mediators in marine evolution. ix
