The Great Barrier Reef has and will continue to face countless threats in its lifetime. The reef has survived through millions of disastrous events through the years. The Crown of Thorns Starfish (COTS) is a major threat to the coral reefs which helps destroy the Great Barrier Reef. This threat may be no bigger than a dinner plate, but it is one of the biggest threats to the Great Barrier Reef. Kate Osborne and researchers discovered that Crown of Thorns Starfish were responsible for 36.7% of coral damage, 33.8% caused by storms, 6.5% by disease, 5.6% created by bleaching and 17.4% unknown or multiple causes of the damage to the Great Barrier Reef, as shown in Appendix 1 (The Conversation. 2012).
