Coral reef in the Blue Hole off Dahab in the Red Sea in Egypt.

---

Coral reef in the Blue Hole off Dahab in the Red Sea in Egypt. Like many areas of coral around the world they are increasingly threatened by global warming indiuced coral bleaching. Bleaching is caused when the water temperature rises to a point that the Zooxanthellae cant tolerate. These symbiotic algaes can recover if the water temperatures drop but prolonged heat will eventually kill the coral.
