New research shows sea turtles, penguins and whales swim at optimal depths to minimise the energetic cost of travel.

Not all animals retreat to their shelters in cold weather.

Emperor penguins survive in a ‘Goldilocks zone’ between too much sea ice and too little. Climate change is having an impact.

A new way to deal with ice buildup on airplanes, drones, and wind turbines comes from researchers investigation into penguin feathers.

You can tell how close penguins are to each other by how similar their voices are.
