Adélie penguins are a vital part of the Antarctic food chain – they eat tiny creatures like krill and small fish, and are a source of food for predators like leopard seals and killer whales. By ...

As a result, the seals could no longer reach their normal breeding sites on the continent. Opportunistic Adélie penguins moved in and took over. The recent DNA analysis adds to our understanding ...

The study uncovered traces of birds, seals, and soil invertebrates, confirming that Adélie penguins have lived along this coastline for at least 6,000 years. Scientists were also able to track ...

Scientists have used ancient DNA to help reconstruct 6,000 years of penguin history at the South Pole. The researchers found that Adélie penguins had taken over the habitat of southern elephant ...

These tuxedo-colored penguins are just under 30 inches, which would make them easy prey had they any land enemies. However, ...

Whales, penguins and seals all eat — or eat things that eat — krill. Understanding the critters’ movements could help identify key areas for marine conservation. Krill use their antennae to ...

This remains to be elucidated. “We hypothesize that Antarctic krill are avoiding the odor of ground-up krill and fish in the penguins’ guano. We thus expect krill to show similar swimming behaviors ...
