There is a hidden world under the ocean.
Scientists have actually discovered many new life forms and ecosystems in the recent years.
Under the ocean are chemosynthetic ecosystems which are found in microscopic cracks in the ocean floor and are powered by chemical reactions with seawater and rocks instead of sunlight.
They are also home to several different life forms which include bacteria, snails and worms.
Deep beneath the ocean floor off the Pacific Northwest coast, scientists have also described the existence of a potentially vast realm of life, one almost completely disconnected from the world above.
Also while using a robotic arm to flip over bits of the sea floor, researchers have also found cave systems filled with a subsurface fluid.
A network of cracks and crevices created a maze in which worms, snails, microscopic larvae, and bacteria are flourishing.
95 percent of the ocean is also unexplored.
The reason why 95 percent of the ocean is unexplored is because most parts of the ocean are extremely difficult to get to, and it's incredibly expensive to do so.
Scientists often rely on sonar, which can generate maps of the seafloor but leaves many questions unanswered.
