A juvenile male Antarctic fur seal (Arctocephalus gazella) on South Georgia Island
The Antarctic fur seal (Arctocephalus gazella) feeds mostly on krill (Euphausia superba). A recent found that fur seals adjust their foraging activity to track the highly variable distribution and density of krill. The number of dives per bout and length of time per dive were shown to maximize the energy intake rate of the seals over the long term. This photograph originally appeared on the cover of Ecology (85:2) in February of 2004.
