It might sound like 1.5 million penguins are a hard thing to miss. However, that is indeed the case with this super-colony of Adélie penguins (Pygoscelis Adeliae) who have managed to remain undetected for decades in the Danger Islands of Antarctica. The remote, difficult to access, landmass, which lies off the continent’s northern tip, is always surrounded by thick ice. It was, therefore, believed to be uninhabitable and largely ignored by scientists.
