ABSTRACT
The behavior of cephalopod molluscs offers a fertile area of research for comparative psychol ogy because these animals have developed an extensive repertoire of behaviors and a major emphasis on learning. Yet they are minimally related to other groups, vertebrates and insects, whose behavior is both complex and intensely studied. A comparative approach to behavior has primarily been taken in previous work on learning, but new studies exist in communica tion systems and the beginning of comparative cognition. These areas of research will be dis cussed, and recent or review articles cited.
