What is unique about the Acropora species of corals?
Some of its species are known as table coral, elkhorn coral, and staghorn coral. Over 149 species are described. Acropora species are some of the major reef corals responsible for building the immense calcium carbonate substructure that supports the thin living skin of a reef.
What type of coral is Acropora?
Acropora (Oken, 1815) is the type genus of the hard coral family Acroporidae (class Anthozoa, order Scleractinia of the phylum Cnidaria). Currently, around 120–140 living species are recognized in this genus, but new species are still being discovered in both living and fossil coral assemblages.

What is unique about the Acropora species of corals compared to most others?
what is unique about the acropora species of corals, compared to most others? Acropora species of coral differ from most corals in that they have two kinds of polyps. when fragmentation occurs with corals the fragments are essentailly dead?
Is Acropora aggressive?
Placement/Aggression Although they don’t look it, Acropora are an aggressive coral. They don’t have stinging sweeper tentacles or engage in chemical warfare but they pack a powerful sting especially to nearby SPS.
Why does Acropora turn white?
Coral bleaching, a process by which reef-building corals lose their algae and turn white, has long thought to be a result of faulty photosynthesis caused by high temperatures. But new research shows that bleaching can occur at night, too.
Is coral an animal?
Corals are animals, though, because they do not make their own food, as plants do. Most structures that we call “coral” are, in fact, made up of hundreds to thousands of tiny coral creatures called polyps.
Why is Acropora important?
Acropora are also known as staghorn corals. They are able to grow much faster than many other coral groups and their limestone skeletons are important to reef building around the world. Their loss would have dramatic consequences for marine life, and the millions of people who rely on reefs for food and income.
What does Acropora coral eat?
zooplankton
Habitat and diet Like other corals in the Acropora genus, staghorn corals use tiny, stinging tentacles to snatch and eat small aquatic animals known as zooplankton. Staghorn corals are also nocturnal predators, waiting until the sun goes down before they unfurl their tentacles and start hunting.
Is Acropora millepora hard or soft coral?
Acropora millepora is a hard coral. Starting from a single embryonic cell, it has been found to reach 5.1 mm in diameter during a period of 9.3 months (Dubinsky, 1990). This species grows mostly vertically, which leads to a bushy morphology that is semi-erect.
What is the main threat to Acropora millepora?
The main threat affecting Acropora millepora is the destruction of the coral reefs where it lives. Although relatively common it is a shallow water species and susceptible to bleaching and coral diseases. It is also collected for the reef aquarium trade.
How many species of Acropora are there?
Acropora. Some of its species are known as table coral, elkhorn coral, and staghorn coral. Over 149 species are described. Acropora species are some of the major reef corals responsible for building the immense calcium carbonate substructure that supports the thin living skin of a reef.
What is the minimum age of maturation in Acropora?
In almost all species of Acropora, individuals have a mandatory threshold size that they must attain before sexual reproduction will proceed. Once this size is met, reproductive output usually increases as a function of body size. The characteristic colony size at maturation usually corresponds to a minimum puberty age of 1-3 years (Hall, 1996).
