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. The reasons for the deep dives and long "road trips" are unclear. As Mark Erdmann, marine scientist with Conservation International who is studying whale sharks, said: "It's a reminder of just how little we know, even today, about life in the sea." We've collected some awesome videos on this topic. Watch them now to learn more.
