recently a number of previously unknown creatures have been discovered in extreme depths of the ocean. While i found some of them truly amazing in their appearance, some others look like some genetic mistakes which have been banned to the extreme darkness of the ocean floor. Given that more than two thirds of our planet are covered by water it is hard to imagine what else lurks down there. All our attempts of exploration have been focusing on distance, height, space, but little on depth. Because this -literally - is the only place without any glimse of light at all. Total darkness. Will they be looking for oil down there some day ?
