The Abyss
The deepest place in the oceans on Earth is the Mariana Trench in the Pacific, it is also known as The Abyss....it is about 36,000 feet or 10,000 metres deep.....so it is deeper than Mt. Everest is high.....Professor August Piccard designed a Bathyscape that descended to that depth and found all manner of strange acquatic life and terrain down there....This is my interpretation of what might also be there, underwater Volcanoes, wierd shells and other unimaginable things...
