Analysing seabed imagery data spanning 5,000 km and >50,000 megafaunal specimens across the Clarion–Clipperton Zone abyssal plain in the northeast Pacific, the authors identify two distinct biogeographical provinces in which taxa that are dependent on calcium carbonate structures are restricted to depths above 4,300–4,880 m.
