Acropora Hyacinthus is known as a peaceful variety of coral thriving mainly in tropical zones where the waters are consistent with high levels of pH, calcium and alkalinity levels.
This saltwater species is normally characterized by thin, finely structured branches of a green or gray color, while their general area of occurrence spans across multiple regions in the Indian and Pacific Oceans.
Unique Growth and Properties
A unique coral with fine, neatly shaped, vertically directed branchlets, Acropora Hyacinthus are known for their colorful appearance and distinct axial corallites. Aside from the most prevalent types of Hyacinthus specimens which are normally green, light blue or gray, the coral has also been found in brown or uniform cream shapes in various areas where it is known to grow.
In terms of depth, this species of coral can normally be found in areas where the reef stretches 5-20 meters beneath the surface of the water, and particular specimens have been located both at the top and bottom of reef slopes, with those found at lower depths being more flattened as a result of increased pressure.
Hyacintus corals spawn every year in the month of October in regions such as French Polynesia, and their increased life cycle often makes them the dominant species in most of the reefs they inhabit.
Mainly thriving in sheltered regions it has also been noted that some of the larger clusters can withstand difficult circumstances more easily, the growth of this tropical coral being sometimes observed on reef edges just as often as it is found on slopes, submerged reefs and outer reef flats.
Prevalence of the Acropora Hyacinthus Coral
This species of Acropora is considered by many scientists to be one of the most abundant corals prevalent in any outer reef slopes situated in western Pacific areas. Despite this fact, their occurrence is even more frequent in regions close to Australia, Indonesia, southwest China and the Philippines, with some populations spotted near Madagascar, the Red Sea, Sri Lanka and other locations in the western part of the Indian Ocean.
Their habitats often consist of upper reef slopes and flats as well, and they have often been associated with similar species, such as Acropora Spicifera and Acropora Tanegashimensis.
In spite of its widespread occurrence, this type of Acropora coral is still labeled as near threatened, mainly as a result of the extensive reef population reduction that has been a problem in recent years throughout south Asia and the northern part of the Indian Ocean.
Nevertheless, Acropora Hyacinthus boasts a level of superior genetic, which has had a significant effect in increasing its resilience to most of the elements that have caused population reduction in the case of other Acropora species.
