A group of fish is seen schooling near the wreck of a ship in the Red Sea off the southern Israeli resort city of Eilat on June 12, 2017. Global warming has in recent years caused colourful coral reefs to bleach and die around the world -- but not in the Gulf of Eilat, or Aqaba, part of the northern Red Sea. At the Interuniversity Institute for Marine Sciences in southern Israeli resort city Eilat, dozens of aquariums have been lined up in rows just off the Red Sea shore containing samples of local corals. / AFP PHOTO / MENAHEM KAHANA
