  1. Deployment dates, lengths and the number of foraging trips are listed per individual. Dive depth is mean (\(\bar{X}\)) ± standard deviation (SD). Listed mass obtained during recovery capture. Target prey: 1 Antarctic fur seal adult, 2 Antarctic fur seal pup, 3 notothen fish, 4 penguin. Carcass indicates the consumption of a scavenged/cached carcass within an individual’s video record. Seal 394Y made no capture attempts within the video record. Hunting tactics that were successful >50% of the time are highlighted in italics.
