Omri Bronstein from the University of Tel Aviv, examines a jar containing Echinothrix Calamaris sea urchins, in the storage facility at the Steinhardt Museum of Natural History in the Israeli Mediterranean coastal city of Tel Aviv, on August 21, 2023. The Red Sea's spectacular coral reefs face a new threat, marine biologists warn, the mass death of sea urchins that may be caused by a mystery disease. Because the long-spined creatures feed on algae that can suffocate corals, their die-off could «destroy our entire coral reef ecosystem,» a scientist said. (Photo by JACK GUEZ / AFP)
