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