  • Hard coral
  • Coral reefs by Aiden and Dan

    1. 1. The Great Barrier Reef<br />How it was made... <br />By Aiden and Dan<br />
    2. 2. Hard Coral<br />This picture is of an adult polyps skeleton. This is attached to a reef.<br />It was born from a coral polyp and its waste comes out of its mouth. <br />
    3. 3. Soft Coral<br />Soft coral is a category of coral that doesn't have an outer skeleton and also doesn't have any defence mechanisms. <br />Sea anemones<br />Soft Coral<br />
    4. 4. Where is the Great Barrier Reef?<br />The Great Barrier Reef is of the coast of Queensland near Cairns and is found in North East of Australia.<br />Many people from all over the world come to admire all of it beautiful marine life.<br />
    5. 5. Fauna<br />The Great Barrier Reef has six of the worlds seven species of marine sea turtle, more than one thousand five hundred species of fish and lots more marine life. <br />
    6. 6. Flora<br />Sea grass is a category of grass that lives in the sea that has no defence mechanisms, this is mostly eaten by Dugongs. <br />Algae is a watery plant that give s coral their colour and lives in humid places.<br />
    7. 7. Three ways Coral reefs are ruined<br />One way a coral reef is ruined is from oil spills.<br />Another way they are ruined is by ship anchors ripping up the coral.<br />The worst way is the Crown-Of-Thorns-Starfish sucking up the coral polyps.<br />
    8. 8. Crown-Of-Thorns-Starfish<br />This is so hurtful to the reef because it is sucking up the coral polyps.<br />It lives on top of dead, bleached coral.<br />This can be stopped if we don’t kill the fish that eat them in the reef.<br />
    9. 9. Oil Spills<br />An oil spill happens when a ship gets a hole in it and all of its oil comes out.<br />Fish die from oil spills that not only affect them, they also affect coral and anemones. <br />
    10. 10. Ship Anchors<br />Ship anchors affect the coral reef by ripping up the coral.<br /> They also might kill animals by crushing them when the anchor is thrown down in the water.<br />
    11. 11. What is stopping the threats<br />We can take away the Crown-Of-Thorns Starfish by not overfishing the Trumpet shell, Triggerfish and the Triton Fish.<br />Oil spills and ship anchors had nothing to do with the nature humans just have to be more careful.<br />
