No matter how deep you can imagine the oceans to be, there’s almost always something that lies deeper. A new video takes you into the heart of the oceans and everything that could be lurking underneath.

Just how deep is deep? if you could turn Mount Everest upside down and submerge it entirely, its tip would go nowhere near the bottom of the ocean.

Go deeper, and every level hides wonderful (and sometimes terrifying) creatures which we will not be able to see, for these are at depths that most humans cannot reach. Or even fathom.

The oceans are an alternate world, with perpetual darkness, massive squids, black dragonfish, remnants from shipwrecks, and lots more we cannot even visualise.
