Climate Warming Threatens Antarctic King Penguins
- King penguins that feed on fish and squid at the northern edges of Antarctica are threatened by global warming, which is cutting down on their food supply, researchers reported on Monday. King penguins, the second-largest species after emperor penguins, are at the top of the food chain in their sub-Antarctic environment, thriving on small fish and squid rather than the tiny krill and other crustaceans that sea mammals favor.
