Photos by Pete McBride pedromcbride | There are 18 species of penguins on Earth, each with its own distinguishing characteristics. King penguins (first photo) are the second largest, and easy to spot with their prominent yellow-orange feathers. Gentoo penguins (second) have bright beaks and a white patch on their heads. They swim up to 22 miles (35 km) per hour, making them the fastest diving bird. I've been lucky to see these and many more penguin types in Antarctica and on the islands north of the continent, where a warming climate puts pressures on all penguin species.
