Death of Coral due to Coral Bleaching

Death of coral due to coral bleaching 

Shock and horror! Unexpectedly one summer, large sections of the Great Barrier Reef turned white. On closer inspection the coral polyps were no longer colourful. After a few weeks in some areas the coral polyps died leaving the white limestone skeleton of the reef exposed, while in other areas it took years for the coral reefs to fully recover. What was going on?
