Hello MARMAMers:
On behalf of the authors, I am very happy to announce our new note which is now available online: Smultea, M.A., C.E. Bacon, K. Lomac-MacNair, I. Visser, and J. Bredvik. (2014). Rare Mixed-Species Associations Between Sperm Whales and Risso's and Northern Right Whale Dolphins Off the Southern California Bight: Kleptoparasitism and Social Parasitism? Northwestern Naturalist 95(1):43-49. Abstract: Inter-specific behavioral interactions between large whales and small odontocetes are rarely described and little understood. Reasons for such associations have been proposed but are difficult to substantiate empirically given the challenges inherent with studying deep- and long-diving cetaceans at sea. Proposed reasons include some of those described for schooling fish, birds, ungulates, and primates, such as reduced predation through the dilution or predator startle effect, competition for resources, aggression, kleptoparasitism, social parasitism, and play and sociality Herein, we describe the first published social interactions of Sperm Whales (*Physeter macrocephalus*), Risso's Dolphins (*Grampus griseus*), and Northern Right Whale Dolphins (*Lissodelphis borealis*) as photo- and video-documented off southern California in spring 2011.
