Deepest fish in the sea is the undisputed king of the Mariana Trench
Miles below the surface of the Mariana Trench, marine life looks totally different from what most people are used to. Instead of big or menacing, the creatures that roam the deepest parts of the ocean are quite small, translucent, and scaleless. At such depths, few organisms are able to survive, so much so that not even some of our submersibles can withstand the ungodly pressure. Yet life always finds a way.
