Though all seven species of sea turtles are threatened or endangered, they are still found in every ocean except the Arctic. Believed to use the Earth's magnetic field to navigate, sea turtles have an extraordinary sense of time and location, and most species return to nest at the exact place where they were born. Certain species even swim ashore together in a single, mass arrival. After a few months, hundreds of hatchlings dig their way out of the nests and seek the ocean. How do they find it?

Officially called the Ardennes Offensive, this major German counter-offensive on the Western Front during WWII was the largest and bloodiest battle fought by the US Army during the war.
