Loggerhead sea turtles do an excited "turtle dance" when anticipating food. It's adorable, of course, but it has also allowed scientists to understand better how the turtles navigate. Scientists have theorized that sea turtles memorize coordinates to navigate using a magnetic "map.

Young sea turtles actively swim and choose their paths instead of drifting. New satellite tracking reveals their movements.

These aquatic reptiles swim thousands of miles across the open ocean to return to the same foraging grounds and nesting sites. They don’t always take the shortest, most direct route, but they do eventually get to where they’re going.

Scientists have used satellite trackers to shed light on the “lost years” of young sea turtles, a period previously shrouded in mystery. For decades, researchers have puzzled over the lives of these creatures between the time they hatch and their return to coastal areas as near-adults. This period can last anywhere from one to 10 years.

Dancing turtles have proved for the first time that some animals use Earth's magnetic field to create a personal map of their favorite spots, scientists said Wednesday.
