(In this underwater photo taken on February 2, 2021, a marine scientist diver from University of Hong Kong’s (HKU) School of Biological Sciences swims above a cuttlefish (centre R) protecting her eggs inside an artificial 3D-printed clay seabed, designed to work as an artificial bed for corals, in the waters of Hoi Ha Wan marine park in Hong Kong. – Around 84 species of coral are found in Hong Kong’s waters, scientists say, more diverse than those found in the Caribbean Sea. Most can be found on remote inlets, far from the sediment filled Pearl River Delta and its busy shipping channels. But like all reefs in a rapidly warming world, they are under enormous pressure.
