A gentoo penguin takes a plunge at Omaha's Henry Doorly Zoo and Aquarium. Gentoos are the fastest underwater swimmers among all penguin species, reaching speeds of more than 20 miles per hour. Jay Storz, Willa Cather Professor of biological sciences, and postdoctoral researcher Anthony Signore are publishing a paper about Emperor Penguins diving abilities. The two are shown with penguins at Henry Doorly Zoo in Omaha. Storz, Signore and their colleagues resurrected two ancient versions of hemoglobin, demonstrating how the blood of penguins evolved to help them better hold their breath while hunting for seafood.
