These outbreaks may be a result of overfishing of the crown-of-thorns starfish's primary predator, the giant triton or they may be a natural phenomenon.

During times of coral bleaching or stresses caused by human activities, outbreaks of the crown-of-thorn starfish.

Crown-of-thorns starfish (COTS) are a native coral predator. On an 'average' reef on the Great Barrier Reef it takes as few as 5-6 adult COTS per hectare to cause a decline in coral cover. But COTS outbreak densities are frequently much higher than this and result in massive reductions in coral cover. This puts added pressure on the reef in.
