Humans are known to exploit plant and animal resources for a variety of purposes. Subsistence is the most obvious of these, but there are also social and technological reasons behind such activities, not to mention ideological and spiritual motives for exploitation. In order to maximise exploitation of resources, human often exploit ecotones, where several ecological zones exist in close proximity. The seashore is such an ecotone, and sea mammals are just one of many groups of resources who are available here. This volume looks to address some of the vast array of coastal adaptations that have occurred during the human past and the role that sea mammals have played in them.
