what did the study show about Antarctic toothfish–another ecologically important fish species in McMurdo Sound, Antarctica?
FUIMAN: Prior to this study, it was thought that Antarctic toothfish are bottom living fish. Well, it turns out that although we saw a relatively small number of toothfish, INSET: SEAL SWIMMING UNDER WATER these occurrences all were in very shallow water. Our seals never encountered toothfish at great depths. We can gain a lot of useful information about prey distributions and prey behavior from this approach of using predators as guided high-speed sampling devices, SEAL UNDERWATER, APPROACHING HOLE IN ICE and this approach could help us with other species of marine animals that are particularly difficult to study in the open ocean.
