The Acropora multiacuta is a type of coral that lives in the ocean. It was first described by F. Nemenzo in 1967. This coral is found in warm, shallow parts of the ocean, like lagoons or on top of reefs. It usually lives at depths of about 3 to 15 meters (10 to 49 feet).
Scientists have listed Acropora multiacuta as a vulnerable species on the IUCN Red List. This means its population is decreasing, and it needs protection. Even though it's not very common, it can be found in a wide area, including parts of Indonesia and Australia's Great Barrier Reef. It is also protected under CITES Appendix II, which controls trade of endangered species.
What Does It Look Like?
Acropora multiacuta corals grow in large, thick groups with many branches. These branches have long, straight coral structures called axial corallites. These structures get thinner towards the end of the branches. The coral is often white or cream in color. Smaller, new corallites can grow below the main ones, forming little branchlets.
This coral is similar to other types like Acropora fastigata and Acropora suharsonoi. It lives in warm, shallow ocean reefs, on rocks, reef walls, and in lagoon areas where there might be some waves. It can even be the main type of coral found in some places. It lives at depths of about 3 to 15 meters (10 to 49 feet) and is made of a strong material called aragonite, which is a form of calcium carbonate.
Where Does It Live?
Even though Acropora multiacuta is generally rare, it can be found in many places. These include the Indian Ocean, the Indo-Pacific region, the western Pacific, the Solomon Islands, Southeast Asia, Eastern Australia, Raja Ampat, and Papua New Guinea. It is quite common in Australia's Great Barrier Reef and also lives in two areas of Indonesia. This coral usually grows in groups.
The population of Acropora multiacuta is shrinking. It faces several threats, including climate change and rising ocean temperatures. Warmer water can cause coral coral bleaching, where the coral turns white and can die. Other threats include coral diseases, damage to reefs, and being eaten by predators like the Crown-of-thorns starfish (Acanthaster planci). Human activities also pose a risk. Because it is vulnerable, this coral is listed under CITES Appendix II, which helps control its trade. It might also be found in Marine Protected Areas, which are special ocean areas where marine life is protected.
How Was It Discovered?
The Acropora multiacuta coral was first officially described by F. Nemenzo in 1967. This happened in the Philippines.
