Coral reefs consist of individual animals called coral polyps and their hard exoskeletons. cal coastlines is suitable for coral reefs. Other environmental factors, such as the amount of salt in the water, or salinity, can limit coral growth. Corals require a.
Reef-building corals have symbiotic algae. • Symbiosis: 2 species closely interacting in a mutually beneficial way. • dinoflagellate that lives in the coral tissue. – Photosynthesizes: corals with symbionts must live in well-lit water. • Coral benefit: algae change internal chemistry to aid in building a strong skeleton rapidly; also
Coral reefs are diverse underwater ecosystems held together by calcium carbonate structures secreted by corals. Coral reefs are built by colonies of tiny animals found in marine water that contain few nutrients. Most coral reefs are built from stony corals, which in turn consist of polyps that cluster in groups. The polyps
23 Sep 2002 Coral reefs are one of the most biologically diverse ecosystems in the world – they occupy less than 1% of the ocean floor, but are inhabited by at least 25% of all marine species. Thirty-two of the 33 animal phyla are found on coral reefs, compared with nine in tropi- cal rain forests. Due to their unique

destructive fisheries, coastal construction, nutrient enrichment, increased runoff and sedimentation, and the introduction of nonindigenous invasive species have caused phase shifts away from corals. Already ?20% of the world's reefs are lost and ?26% are under imminent threat. Conservation science of coral reefs is well
reef. Coral reefs rival that other great tropical community, the rain forest, in their beauty, richness, and complexity. Tropical rain forests and coral reefs are also similar in that the basic physical structure of both communities is pro- duced by organisms. Both reef-building corals and the giant trees of a rain forest create a
