The genus Acropora has the largest number of species of all the hard corals, and they are among the important building blocks of a reef. Larger colonies are more commonly seen on undisturbed and remote reefs. Many species grow into branching forms that give rise to common names like \

Coral reefs are the one of earths most complex ecosystems, containing over 800 species of corals and one million animal and plant species. Here we see a shallow coral reef consisting of hard Staghorn Coral (Acropora)  supporting shoals of Indian Damselfish (Dascyllus cameus).  They are using the reef as a natural protection from predators.  This coral, although on the whole healthy, is showing signs of distress.  75% of the worlds coral reefs are now classed as 'Threatened,' with 60% of most reefs having local damage from anchors, overfishing, coral bleaching, disease and pollution.  Here the tips of the coral are beginning to bleach.

At this very healthy reef at Karang Rembang, a sea mountain north of Tayandu Island, this beautyful Acropora table coral dominates the scenery. \nAcropora corals are among the fastest growing corals on reefs, they are excellent reef-builders. However, their speed of growth is balanced by the fragility of some of the structures, as they are easily damaged in storms allowing other coral species a chance of growth. \nKarang Rembang, north of Tayandu Island, Indonesia, 5°27'4.812 S 132°23'54.732 E at 16m depth
