Gentoo penguins on Cuverville Island in the western Antarctic. Like seals and whales, they eat krill, an inch-long shrimp-like crustacean that forms the basis of the Southern Ocean food chain. But penguin-watchers say the krill are getting scarcer in the western Antarctic peninsula, under threat from climate change and fishing. Credit: Eitan Abramovich/AFP via Getty Images
