A new paper on Antarctic killer whales has been published in the Journal of Cetacean Research and Management: Observations of killer whales off East Antarctica, 82°-95°E, in 2009. 2012. Olson, P.A., Ensor, P., and Kuningas, S. *J. Cetacean Res. Manage*. 12(1): 61-64. ABSTRACT Observations of killer whales (*Orcinus orca*) during a survey off east Antarctica, 082° - 095°E revealed previously undescribed variations in pigmentation and group associations. During the survey 24 killer whale groups were sighted south of 60°S and classified, when possible, to Types A, B, or C (Pitman and Ensor 2003) based on their external morphology. Sufficient observation was available for nine groups to be classified: 2 groups of Type A; 1 mixed group of Type A and Type B; 3 groups of Type C; and 3 groups with eyepatch pigmentation intermediate in size between Types B and C. These whales may represent an intergrade between Types B and C or a previously unrecognized form. One of the 'intermediate' groups was observed feeding in a multi-species aggregation with other cetaceans in deep water. Clearly distinguishable Type A and Type B whales were observed feeding together in a mixed aggregation, the first time that this has been documented.
