Growing up to 65 feet and weighing 10 tons, the whale shark is the largest fish in the world; it is three times the size of a great white. Scientists have recently discovered that whale sharks travel to great depths, sometimes up to 6,000 feet, and some even make long journeys -- sometime as far as 800 miles -- from home.
