In the entire solar system Earth is the only planet that has water in its liquid form in such quantities. Scientists have calculated that 70% of our planet is covered by water; small wonder then that humans have always been so fascinated by the oceans and what lies beneath. Today while we still have so much more of the ocean realm to uncover we have discovered enough to know that beneath the waves lies a vast treasure-trove of rich and diverse life.
