Why This Reef Belongs to Sharks After Dark

The Red Sea is saltier and warmer than almost any ocean on Earth, and the reef that grows there changes owner completely once the light goes. This documentary follows fourteen hours on a Red Sea fringing reef off the Egyptian coast. Cut off from the Indian Ocean by a shallow strait and losing water faster to evaporation than any river can replace, this basin is hyper-saline and unusually warm — conditions that killed off most competitors and left behind a reef with an exceptionally high rate of endemic species. You will see Spinner Dolphins arriving from the deep trenches at first light, Hawksbill Turtles stripping the toxic sponges that would otherwise smother the coral, Sohal Surgeonfish and Emperor Angelfish over the Acropora gardens, Dugongs and turtles waiting out the worst of the midday heat, a Giant Moray Eel holding its crevice, and a Titan Triggerfish biting clean through living coral as the tide turns. Then the sun drops, the coral plateau empties, and Oceanic Whitetip Sharks come in from the blue. Filmed as a continuous day cycle, from dawn on the reef flat to the arrival of the night shift.
