It's a vass alien world down there... Giant monsters swim past, probably starving, for meals haven't come by for days... We are 11,034 meters (36,201 feet) deep in the the Mariana Trench, the worlds deepest spot on Earth. First, only specially adapted marine life can live there, for its frigid cold temperatures and crushing water pressure limit life in the pitch black abyss. Angler Fish and Crabs are few of the many species in the Mariana Trench. Next, its floor contains hydrothermal vents formed by spreading tectonic plates which release hydrogen sulfide and other minerals into the ocean water. Furthermore, it is consumed by barophilic bacteria which then are consumed by microorganisms which are eaten by larger fish. The temperature around the vents can reach up to 572 degrees Fahrenheit! Then, different proteins allow fish to adapt to the extremely cold temperatures of the surrounding environment of water. The proteins also allow the animals to eat, process food, and reproduce. Another extraordinary characteristic of marine life at that depth is their longevity. Many of the adapted animals have lifespans over 100 years! There are more than just Bythograea thermydron (Vent Crabs) and angler fish in the Mariana depths, because when the Challenger Deep took a mud sample of the bottom, it yielded more than 200 microorganisms. The ocean floor at great depths consists of pelagic sediment composed of shells, animal skeletons, decaying microorganisms, and dead plants. Those are the amazing features of life in the Mariana Trench.
