Figure S1. Remains of a Weddell seal killed by pack ice killer whales (Table 1, Group 3, Event 21) near Adelaide Island, Antarctica, 30 January 2009. Shown here is the intact skin and blubber from the entire upper body after the whales removed the axial body (except for the skull) and posterior extremities. The sets of parallel dark lines on the lower part of the skin are killer whale tooth rake marks. The arrow points to the top of the exposed skull—the whales slit the skin along the back of the neck and pulled it forward over the back of the head, exposing the anterior spinal column and skull.

Figure S2. The head of the same Weddell seal from Figure S1 after we pulled the skin back into position to show that the head was undamaged during the kill and subsequent “butchering” process. The skin was cut behind the neck and reflected forward apparently to expose the spine so that it could be disarticulated from the base of the skull (see text). Photo: K. Jeffs.
