ANTARCTICA-ENVIRONMENT-KRILL-PENGUINS

View of Gentoo penguins in Cuverville Island, in the western Antarctic peninsula on March 04, 2016. Waddling over the rocks, legions of penguins hurl themselves into the icy waters of Antarctica, foraging to feed their young. 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.
