The emperor penguins of Antarctica live on a diet of fish and crustaceans obtained from the cold Antarctic seawaters. During their annual breeding cycle, however, they migrate across the frozen continent to their breeding grounds 50 miles away from the sea (and 50 miles away from their source of food). For over two months, the male emperor penguins care for and incubate eggs, while the females return to the sea to feed. During this time, a male penguin can lose up to 50% of its biomass (by dry weight). Where does this biomass go?
