Ocean abysses are deep, dark regions of the ocean floor that are located far below the surface. They are some of the deepest parts of the ocean, often reaching DEPTHS of several thousand meters. These areas are characterized by extreme pressure and low temperatures, making them inhospitable to most forms of life. Ocean abysses are home to a variety of unique species, including some of the deepest-dwelling fish and invertebrates known to science. They are also important sources of valuable minerals and other resources.
