The three main types of coral reefs are fringing, barrier, and atoll. Schools of colorful pennantfish, pyramid, and milletseed butterflyfish live on an atoll reef in the Northwestern Hawaiian Islands.The most common type of reef is the fringing reef. This type of reef grows seaward directly from the shore.They form borders along the shoreline and surrounding islands. When a fringing reef continues to grow upward from a volcanic island that has sunk entirely below sea level, an atoll is formed.he most common type of reef is the fringing reef. This type of reef grows seaward directly from the shore. They form borders along the shoreline and surrounding islands.
Different species of coral grow at different rates depending on water temperature, salinity, turbulence, and the availability of food. The massive corals are the slowest growing species, adding between 5 and 25 millimeters (0.2â1 inch) per year to their length.Branching and staghorn corals can grow much faster, adding as much as 20 centimeters (8 inches) to their branches each year. Coral reefs grow best in warm water (70â85Â° F or 21â29Â° C).Corals prefer clear and shallow water, where lots of sunlight filters through to their symbiotic algae. It is possible to find corals at depths of up to 300 feet (91 meters), but reef-building corals grow poorly below 60â90 feet (18â27 meters).ranching and staghorn corals can grow much faster, adding as much as 20 centimeters (8 inches) to their branches each year.
