..."Most seamounts were formed by undersea volcanoes. They're common in oceanic basins, but only a small fraction of the world's seamounts have been explored. The habitats they create are seen as biological hot spots, hosting a wide range of marine life.
"New estimates suggest that, taken together, seamounts encompass about 28.8 million square kilometers of the Earth's surface," NOAA says. "That's larger than deserts, tundra, or any other single land-based global habitat on the planet."
