Satellite tagging of Humpback whales has lead to some recent discoveries, allowing us to understand a little more about these amazing creatures. According to the scientist, humpback whales can travel thousands of miles deep underwater in an astonishingly straight line - and the sun, moon and stars may be why they never get lost. But it has now emerged the huge mammals may use a combination of the sun's position, Earth's magnetism and even star maps to guide their journeys, which can up 10,000 miles long. Most of the whales in the experiment, which were tracked between 2003 and 2010, maintained an almost dead-straight course, deviating by less than one degree - despite the effects of weather and ocean currents.
