Some areas were hit particularly hard, like the Great Barrier Reef in Australia, where hundreds of miles of coral were bleached. The largest coral reef is Australia’s Great Barrier Reef, which began growing about 20,000 years ago. Coral polyps, the animals primarily responsible for building reefs, can take many forms: large reef building colonies, graceful flowing fans, and even small, solitary organisms. Coral reefs are large underwater ecosystems made up of the skeletons of corals. About 25% of the ocean's fish depend on healthy coral reefs. The stronger currents and waves deliver more food for the ecosystem that creates the reef structure. Coral reefs are the main habitat for herbivorous fish species such as parrotfish, rabbitfish, surgeonfish, damselfish and coralfish. Reefs help seagrass and other sea plants survive in the area. Other threats are caused by people, including pollution, sedimentation, unsustainable fishing practices, and climate change, which is raising ocean temperatures and causing ocean acidification. Threats to coral reefs Fact 8: Reefs are where many fish and sea creatures choose to spawn. They also are more likely to be found in tropical oceans, as the water is clearer and warmer.
