What are Coral Reefs?

Corals are ancient animals related to jellyfish and anemones. An individual coral is known as a polyp, a very small and simple organism consisting mostly of a stomach topped by a tentacle-bearing mouth. The polyps extend their tentacles at night to sting and ingest tiny organisms called plankton and other small creatures.

Top 10 Things To Do On The Great Barrier Reef

Visit the Reef in style on board ocean spirit, the 32-metre (105 foot), high-performance catamaran. Sailing daily from Cairns to Michaelmas Cay, you can dive and snorkel the Reef among the turtles and colourful fish, lie on the deck and soak up the sun or enjoy a glass-bottomed boat tour. Michaelmas Cay is also home to over 23 species of seabirds and is one of the most significant bird sanctuaries on the Great Barrier Reef.

Recreational Activities

Cooperation and Competition

On coral reefs, some shrimp species called "cleaners" play a highly significant role in the life of the coral reef community, gaining food by removing parasites from fishes or other invertebrates.

Most crabs are omnivores, feeding on a wide variety of food items including algae, worms, mollusks, bacteria, other crustaceans, fungi, and even detritus.

Crustaceans are scavengers, cleansing the reef of decaying animal remains. Others are active predators or omnivores. Many are preyed upon by coral reef fishes.


Coral reefs are also being degraded by many other factors. The list of problems can seem endless: overfishing, fishing using cyanide and dynamite, pollution from sewage and agriculture, massive outbreaks of predatory starfish, invasive species, and sedimentation from poor land use practices.

Endangered Species

The whole coral reef ecosystem is endangered because of pollution and human presence.

Manatees are hunted and killed often.

Biome Changes

Global warming is endangering this biome

Global Importance

This biome is important because it provides food and its variety of fish, crabs, shrimp and many other types of animals.

5 Fascinating Facts About Coral Reefs & The Hyberlink

1. Corals are not plants. They're actually animals and are are, amazingly enough, relatives of jellyfish and anemones.

2. Though corals are animals, they do rely on photosynthesis to survive. But the coral polyps aren't doing the actual photosynthesizing. Microscopic algae, or zooxanthellae, live within the cells lining the digestive cavity of the polyp. As much as 90 percent of the energy a polyp needs comes from this symbiotic relationship. The other 10 percent comes from hunting the polyp does by extending its tentacles to catch prey.

3. Reefs formed by corals are one of the most bio diverse marine areas on the planet, housing hundreds and even thousands of species. The diversity is due to the fact that reefs are an important location for finding food, shelter, mates and places to reproduce. Reefs also act as nurseries for large fish species, keeping them safe until they are large enough to strike out into the deeper ocean.

4. Coral reefs are important to the development of new medicines. According to NOAA, "Coral reef plants and animals are important sources of new medicines being developed to treat cancer, arthritis, human bacterial infections, Alzheimer’s disease, heart disease, viruses, and other diseases."

5. Coral reefs are so valuable to the fishing and tourism industries, as well as protecting shorelines from storm damage, that destroying just 1 kilometer of coral reef means the loss of between $137,000 to $1,200,000 over a 25-year period, according to theWorld Resources Institute. And yet, nearly 60 percent of the world's coral reefs are threatened by human activity.
