n a mound of living creatures with hard shell skeletons (coral) building a home in shallow salt water locations As animals die others grow onto the dead skeletons and continue the building of the reef The mound usually encompasses tropical islands
a wave-resistant structure resulting from cementation processes and the skeletal construction of hermatypic corals, calcareous algae, and other calcium carbonate-secreting organisms
a ridge or mound made by colonies of tiny coral animals; found only in shallow regions of tropical oceans
A coral reef is a long narrow mass of coral and other substances, the top of which is usually just above or just below the surface of the sea. An unspoilt coral reef encloses the bay. An erosion-resistant marine ridge or mound consisting chiefly of compacted coral together with algal material and biochemically deposited magnesium and calcium carbonates. a line of hard rocks formed by coral, found in warm sea water that is not very deep. Ridge or hummock formed in shallow ocean areas from the external skeletons of corals. The skeleton consists of calcium carbonate (CaCO3), or limestone. A coral reef may grow into a permanent coral island, or it may take one of four principal forms. Fringing reefs consist of a flat reef area around a nonreef island. Barrier reefs may lie a mile or more offshore, separated from the landmass by a lagoon or channel. Atolls are circular reefs without a central landmass. Patch reefs have irregular tablelike or pinnacle features. Smaller patches occur inside atoll lagoons; larger patches occur as isolated parts of any of the other three reef categories, and they sometimes occur completely separate from other kinds of reefs
complex tropical marine ecosystem dominated by soft and hard (stony) corals, anemones and sea fans Stony corals are microscopic animals with an outer skeleton of calcium carbonate that form colonies and are responsible for reef building
Marine feature produced by numerous colonies of tiny coral animals, called polyps, that create calcium carbonate structures around themselves for protection When the corals die, their vacant exterior skeletons form layers that cause the reef to grow Coral reefs are found in the coastal zones of warm tropical and subtropical oceans
A marine ridge or mound comprised primarily of coral, together with algal and mineral components, which forms the foundation for a biologically rich and diverse ecosystem
