The seas and the oceans make up a complex three-dimensional world that covers 71% of the planet's surface. This world is home to thousands of more or less known marine animals. Many of them are still undiscovered. The largest recorded depth is in the Pacific Ocean, 10,882 meters. Deep water is considered a special area because there is very high water pressure and there is no light. And yet there is life.
