Extract

New micro-technology with links to satellites has revolutionized the collection of information on the foraging movements of marine animals, but observations of actual foraging are still very rare. Here we describe foraging by killer whales (Orcinus orca (L.)), minke whales (Balaenoptera bonaerensis Burmeister), Adélie penguins (Pygoscelis adeliae (Hombron & Jacquinot)) and emperor penguins (Aptenodytes forsteri Gray), in all cases we believe feeding on fish, in the south-western Ross Sea, Antarctica.
