According to the National Oceanic and Atmospheric Administration, coral reefs are formed when coral larvae attach themselves to rocks or other hard surfaces found under water along the edges of islands and along coasts. Additionally, plants may also accumulate within the reef. The process is slow an
Coral reefs start to form when coral larvae attach to rocks or hard surfaces that are submerged under water. Coral polyps secrete calcium carbonate, closing off each layer as they grow bigger. Each polyp bonds itself to other polyps, eventually forming reef structures.
Coral reefs are important to the biodiversity of Earth. According to the U.S. National Oceanic and Atmospheric Administration, coral reefs house more species than any other marine habitat, making them the equivalent of an underwater rain forest. The life there provides scientists vast opportunities
Coral reefs are endangered due to rising global temperatures, pollution and overfishing. It is estimated that about 1/5 of all coral reefs on the planet have been destroyed. The remaining ones could potentially vanish by 2050.
According to the non-profit project Coral Science, coral reefs are not lodged in soil. The rocky substance in which they are fixed is made by the corals themselves. They live in colonies made of many polyps that build skeletons from the underside of their skin.
Dolphins live near coral reefs, but they do not live in coral reefs. Dolphins, like all other ocean species, benefit from a robust coral reef ecosystem, because reef inhabitants maintain the balance of nutrients that helps to normalize water quality.
One example of a parasitic relationship in coral reefs includes crustaceans from the Copepoda or Isopoda orders, which attach to fish in the reefs, sometimes causing harm but at other times simply holding on and feeding on food particles that float by them. Coral reefs feature organisms that coexist
A coral reef's food chain starts with algae that produce food from water, carbon dioxide and sunlight, which are eaten by microscopic organisms, invertebrates, fish and turtles, which are eaten in turn by predators. All ecosystems, including coral reef ecosystems, have producers, consumers and decom
If the world's coral reefs die off completely, their loss is likely to create hunger in countries that rely on the reefs to attract and sustain fish, economic decline in places that rely on the allure of reefs for tourism and a gap in the world's biodiversity. Ecologist Roger Bradbury wrote in an op
Omnivores living on coral reefs include fishes, crabs and other crustaceans. Coral fishes feed on algae and animals, whereas crabs consume algae, bacteria, fungi, mollusks and worms. The diet of crabs also includes detritus and other crustaceans.
