I don't recall any mention of the estimated proportion of cephalopod on the menu (by weight).Stomach contents regularly contained whole specimens of Patagonian toothfish, and discarded fish heads of that species (fishery waste), which were most likely eaten directly in trawls and scavenged at the bottom, respectively. Other prey items were demersal fishes (mainly the skates Bathyraja irrasa and B. eatonii, and the nototheniids Notothenia rossii and Lepidonotothen squamifrons), benthic invertebrates (e.g. sea stars, ophiurids) and carrion. The stomach of nine sharks contained big chunks of flesh (up to 30 kg), which, in 2 cases, were identified as belonging to fur seals (probably the Antarctic fur seal Arctocephalus gazella).
