Consumers in the Reef


The Nudibranch is a consumer that lives in the Great Barrier Reef. The Nudribranch uses it's bright colors to warn predators away, allowing them to survive. They also use feathery gills to breath under water. Without them they would not be able to live in the Ocean.

Sea Snake

The Sea Snake is a predator that inhabits the Great Barrier Reef. Although the Sea Snake must surface to breathe, it can hold it's breath for up to 2 hours. This gives the snake plenty of time to be under water and to hunt to survive.

Leatherback Turtle

The Leatherback Turtle is a very large consumer that lives in the Great Barrier Reef. The turtles' larges shell protects it from predators and many other dangers that live in the Ocean. The fin-like limbs of the turtle allow it to swim/navigate through the Ocean. Without them the Turtle would not be able to survive.

Underwater Producers

Macroalgae (Halimeda)

Macroalgae are both good and bad Great Barrier Reef. They provide carbon which helps the living organisms in the reef thrive, but they can kill corral and compete for space, causing a great amount of corral degration.


Coral is found in many places in the ocean, one of them is the Great Barrier Reef. One way that corral has adapted to survive is by reproducing both sexually and a sexually. This allows them to continue to reproduce faster.


The Caulerpa is a species of sea grass that lives in the Great Barrier Reef. It is poisonous to most cconsumers that would, in other circumstances, eat it. If the Caulerpa, was not poisonous it would probably be eaten, and therfore may not be able to survive in the Great Barrier Reef.

Global Warming in the Great Barrier Reef

Rising temperatures in the Great Barrier Reef off the coast of Australia are having a negative effect on the plants and animals living there. The increased temperatures are not only causing corral bleaching but are making it harder for its inhabitants to thrive. If temperatures continue to increase creatures may become ill and not grow as much, and may wipe out some inhabitants and species all together. The heat is being caused by global warming. Studies show that the increased temperatures are caused by polution across the world. The fumes and smoke being released from factories and cars into the air goes into the atmosphere and breaks it down, allowing more heat from the Sun to reach the surface of Earth. Some steps have been taken to eliminate some of the pollution but there is still alot being created. To slow-down/ eliminate this problem we must stop releasing the smog toxic gasses, stop using cars and find a way to stop factories from producing the fumes and smoke. If we don't, not only will species and creatures in the Great Barrier Reef be affected but other animal, plants, and people across the world will, too. Eventualy, it will be so unbearably hot there will be more droughts, plants will die, and organisms will be dehydrated. Over time, global warming may completely destroy our planet and wipe out the human race as well as all of the other creatures. If humans don't change their ways, there may not be any other hope. Find out ways for you to help your environment, stop global warming, and save the great barrier reef. Get out, get help, and make a change.
