21. Crown of Thorns Starfish • Prey on coral polyps (which makes up the Great Barrier Reef) • Large outbreaks of these starfish can devastate the reef, such as in 2000 when an outbreak of crown of thorn starfish caused a loss of 66% of live coral • Causes of outbreaks of these starfish are: • they occur in a natural cycle • Poor water quality increases the risk of outbreaks • Overfishing of starfish’s predators Back Next

22. Fishing • Overfishing of keystone species, such as Giant Triton, can disrupt food chains vital to reef life • Fishing causes increased water pollution from boats and catching unwanted species • Fishing causes habitat destruction from anchors and nets Back Next

23. Application • Think about what other types of effects pollution has on the Great Barrier Reef and the world in general. • Once you have done this, you can move on to the practice before the quiz. Back Main Menu
