Scientists working in Antarctica have found that whales, penguins and seals could be facing a food shortage as their favourite snack is in decline.
The British Antarctic Survey discovered that numbers of a tiny shrimp like creature called krill are decreasing.
They say this is bad news for animals living on the frozen continent, as less food around means they are already having fewer babies each year.
Experts reckon that global warming may be affecting the krill population.
