The Pacific, India, the Atlantic, the South (Antarctica) and the Arctic cover 72% of the planet’s surface. At least 230,000 species are found in the oceans, which have a crest length of 1,111 km. Its average depth is 3,790 m and its maximum depth is 10,923 m. The deepest point is in the Mariana Trench in the Pacific Ocean. In 1960, a ship called “El Trieste” successfully reached the bottom of the trench with only 2 men in its crew.
