Humpback Whales (Megaptera novaeangliae) feeding on Krill in Wilhelmena Bay, Antarctic Peninsular and surfacing wth a metre of a zodiak. The whales migrate here in the summer to feed on the Krill. Krill numbers have declined by over 50%. They feed on algae that grows on the underside of sea ice, As the sea ice melts, both algae and krill decline. This shot has penguins resting on an iceberg in the background.
