Coral Reef
Field Of Study- A coral reef is an underwater ecosystem characterized by reef-building corals. Reefs are formed of colonies of coral polyps held together by calcium carbonate. Most coral reefs are built from stony corals, whose polyps cluster in groups. Coral belongs to the class Anthozoa in the animal phylum Cnidaria, which includes sea anemones and jellyfish. Unlike sea anemones, corals secr…
- The worlds largest coral reef is the Great Barrier Reef. The Great Barrier Reef is situated in the Coral Sea, off the coast of Queensland, Australia. The Great Barrier Reef consists of more than 2,900 individual reefs, including 900 islands spanning over 2,300 km or 1400 miles. It takes up an area of about 344,400 km sq or 133,000 sq mi. This data underscores the depths at which coral …
- When alive, corals are colonies of small animals embedded in calcium carbonate shells. Coral heads consist of accumulations of individual animals called polyps, arranged in diverse shapes. Polyps are usually tiny, but they can range in size from a pinhead to 12 inches across. Reef-building or hermatypic corals live only in the photic zone, the depth to which sufficient sunlight p…
- Most coral reefs were formed after the last glacial period when melting ice caused sea level to rise and flood continental shelves. Most coral reefs are less than 10,000 years old. As communities established themselves, the reefs grew upwards, pacing rising sea levels. Reefs that rose too slowly could become drowned, without sufficient light. Coral reefs are found in the deep sea awa…
- The living stony coral polyps and the abundant coralline red and green algae are responsible for the formation of coral reefs. It starts with a small limestone structure and builds up over the years. The buildup takes place in clear warm tropical and subtropical waters. Biologists estimate that more than 1000 species of marine animals live in the coral reef biome, as well as 1,500 wide ran…
- Coral reefs mainly form in the tropics since they favor temperatures between 70- 80 degrees Fahrenheit. They also tend to develop well in areas with a lot of sunlight penetration. Coral reefs need sunlight since individual polyps, which contribute to the growth of corals, contain symbiotic algae. The algae require light to aid photosynthesis.The coral benefits by utilizing some photosy…
- Coral reef biomes are mostly located in shallow tropical regions of the Western Pacific, Indian and Atlantic Oceans. These locations happen to be ideal for growth, settlement, and survival of hard corals. Coral reefs are not able to endure temperatures that plummet below 18 degrees Celsius. This means their habitats are limited to waters ranging from 23°N to 23°S latitude. However, as …
- Coral reefs are estimated to cover 284,300 km2, just under 0.1% of the oceans' surface area. The Indo-Pacific region account for 91.9% of this total. Southeast Asia accounts for 32.3% of that figure, while the Pacific including Australia accounts for 40.8%. Atlantic and Caribbean coral reefs account for 7.6%.

- Coral reefs form some of the world's most productive ecosystems, providing complex and varied marine habitats that support a wide range of other organisms. Fringing reefs just below low tide level have a mutually beneficial relationship with mangrove forests at high tide level and sea grass meadows in between: the reefs protect the mangroves and seagrass from strong currents and w…
- Algae are microscopic in size. They lack true leaves, stems, and roots. Algae are major sources of food for tiny fish species. Algae also play the role of glue that helps the corals reefs to grow to gigantic skeletons. The largest coral reef in the world, the Great Barrier Reef, has about 500 species of algae, as well as blue-green algae (cyanobacteria) that is responsible for the formatio…
- Since Darwin's identification of the three classical reef formations – the fringing reef around a volcanic island becoming a barrier reef and then an atoll – scientists have identified further reef types. While some sources find only three, Thomas and Goudie list four "principal large-scale coral reef types" – the fringing reef, barrier reef, atoll and table reef – while Spalding et al. list fiv…
