The Mariana Deep Sea Trench - a place of dark beauty and extremes - is considered the deepest point in the oceans. Scientists have just made a startling discovery here after a deep-sea probe found it! The long and narrow valley at the bottom of the sea is the result of tectonic activity and home to many highly specialized and bizarre creatures. The latest findings in deep-sea research even suggest that other life forms and possibly entire civilizations exist in the depths, of which we had not the faintest idea until now.
