About this image

Gentoo and Chinstrap penguins on a small ice floe in the ocean near Danko Island, Antarctica. The photographer observed them pushing each other off the floe and swimming in the water as if playing a game of tag. The two species belong to the genus Pygoscelis, Gentoos are P. papua and Chinstraps are P. antarcticus. The two species probably diverged about 14 million years ago. Gentoos are slightly larger than Chinstraps and are the fastest swimmers of all penguin species, reaching speeds of 36 km/h underwater. This image was captured with a Nikon D3 camera and 17-35mm lens in a customised waterproof housing and twin flash units.
