The world's oceans are so underexplored that if you dive deeper than 3,500 meters, there's a good chance to discover a new species unknown to science. There's also a good chance you'll find debris and garbage. Oceans cover more than 70% of the Earth's surface. The average depth of the oceans is about 3.7 kilometers, and since light can only penetrate to a depth of 100 meters, darkness reigns deeper underwater. Let’s push this statement one step further and conclude that since most of the planet is covered by water, it means that most of the Earth exists in total darkness.

We are going to dive deep to the places with most elien conditions! What was found in the deepest places of the ocean?
