The Deep Sea World Beyond Sunlight – From the Edge of Darkness to the Black Abyss: Marine Scientists Census 17,500+ Species and Counting: “Census of Marine Life scientists have inventoried an astonishing abundance, diversity and distribution of deep sea species that have never known sunlight – creatures that somehow manage a living in a frigid black world down to 5,000 meters (~3 miles) below the ocean waves. Revealed via deep-towed cameras, sonar and other vanguard technologies, animals known to thrive in an eternal watery darkness now number 17,650, a diverse collection of species ranging from crabs to shrimp to worms. Most have adapted to diets based on meager droppings from the sunlit layer above, others to diets of bacteria that break down oil, sulfur and methane, the sunken bones of dead whales and other implausible foods.”
