Building blocks of coral skeletons of dead corals are. On the Great Barrier Reef is composed of about 3 thousand. coral reefsand small islands with very diverse areas - from just a few meters to 50 km ². Great Barrier Reef stretches 330 km into the Pacific.Its total area is 259 thousand. km ².


Great Barrier Reef is famous for its corals, although they constitute only 1 / 10 surviving organisms here. On the reef there are at least 350 species of various shapes, sizes and colors. They require the right environment. Reefs are formed only in the saline andwarm waters (temperature maintaining not less than 22 ° C). The water must contain enough oxygen, so it can not be waterstanding and must be sufficiently clear that the sludge did not block the digestive system of coral.
