Anacropora Pillai
''Anacropora'' is a genus of stony corals in the Acroporidae family. They are sometimes called briar corals and there are seven known species. Description Members of this genus are generally fragile corals with branches less than ten centimetres long which form small colonies. The branches are either spreading or may be clustered and are sometimes fused together. The calices are rounded and up to one millimetre in diameter. The area between the calices is porous with numerous small tubercles. There are no axial corallites and the main septa number six with a few more subsidiary ones. The small radial corallites have an ‘empty’ appearance similar to ''Montipora''. The delicate tentacles can often be seen extended during the day. Distribution Members of this genus occur in the Indian Ocean and the western Pacific being found mostly in muddy waters. They are generally uncommon and are not a reef species.

Anacropora Forbesi
''Anacropora forbesi'' is a species of briar coral that can be found in the tropical western and central Indo-Pacific region. It is the type species of the genus '' Anacropora''. Description ''Anacropora forbesi'' is a small coral, branching dichotomously, with slender branches up to in diameter, slightly tapered and with blunt tips. The coenosteum (the stony skeleton of the coral) is smooth and the lower lips of the corallites (the stony cups in which the polyps sit) project slightly. This coral is usually a light brown colour with pale tips to the branches. It is closely related to ''Acropora'' and ''Montipora'' corals, but differs from them in not having a terminal axial corallite at the tip of the branches. Distribution and habitat ''Anacropora forbesi'' is native to the western and central Indo-Pacific. Its range extends from Madagascar, the east coast of Africa and the Red Sea to the northeastern Indian Ocean, Australia, Malaysia, Indonesia, Japan, the Philippines and th ...

Reef
A reef is a ridge or shoal of rock, coral or similar relatively stable material, lying beneath the surface of a natural body of water. Many reefs result from natural, abiotic processes— deposition of sand, wave erosion planing down rock outcrops, etc.—but there are also reefs such as the coral reefs of tropical waters formed by biotic processes dominated by corals and coralline algae, and artificial reefs such as shipwrecks and other anthropogenic underwater structures may occur intentionally or as the result of an accident, and sometimes have a designed role in enhancing the physical complexity of featureless sand bottoms, to attract a more diverse assemblage of organisms. Reefs are often quite near to the surface, but not all definitions require this. Earth's largest coral reef system is the Great Barrier Reef in Australia, at a length of over . Biotic There is a variety of biotic reef types, including oyster reefs and sponge reefs, but the most massive and widely ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Marine Fauna Of Asia
All of the animals living in Asia and its surrounding seas and islands are considered the fauna of Asia. Since there is no natural biogeographic boundary in the west between Europe and Asia. The term "fauna of Asia" is somewhat elusive. Temperate Asia is the eastern part of the Palearctic realm (which in turn is part of the Holarctic), and its south-eastern part belongs to the Indomalayan realm (previously called the ''Oriental region''). Asia shows a notable diversity of habitats, with significant variations in rainfall, altitude, topography, temperature and geological history, which is reflected in its richness and diversity of animal life. Origins of Asian wildlife The formation of the Asian fauna began in the Mesozoic with the splitting of Laurasian supercontinent. Asia blends elements from both ancient supercontinents of Laurasia and Gondwana. Gondwanian elements were introduced from Africa and by India, which detached from Gondwana approximately 90 MYA, carrying its Gondwan ...

Fauna Of The Indian Ocean
Fauna is all of the animal life present in a particular region or time. The corresponding term for plants is ''flora'', and for fungi, it is ''funga''. Flora, fauna, funga and other forms of life are collectively referred to as '' biota''. Zoologists and paleontologists use ''fauna'' to refer to a typical collection of animals found in a specific time or place, e.g. the "Sonoran Desert fauna" or the "Burgess Shale fauna". Paleontologists sometimes refer to a sequence of faunal stages, which is a series of rocks all containing similar fossils. The study of animals of a particular region is called faunistics. Etymology ''Fauna'' comes from the name Fauna, a Roman goddess of earth and fertility, the Roman god Faunus, and the related forest spirits called Fauns. All three words are cognates of the name of the Greek god Pan, and ''panis'' is the Greek equivalent of fauna. ''Fauna'' is also the word for a book that catalogues the animals in such a manner. The term was first used by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cnidarians Of The Pacific Ocean
Cnidaria () is a phylum under kingdom Animalia containing over 11,000 species of aquatic animals found both in freshwater and marine environments, predominantly the latter. Their distinguishing feature is cnidocytes, specialized cells that they use mainly for capturing prey. Their bodies consist of mesoglea, a non-living jelly-like substance, sandwiched between two layers of epithelium that are mostly one cell thick. Cnidarians mostly have two basic body forms: swimming medusae and sessile polyps, both of which are radially symmetrical with mouths surrounded by tentacles that bear cnidocytes. Both forms have a single orifice and body cavity that are used for digestion and respiration. Many cnidarian species produce colonies that are single organisms composed of medusa-like or polyp-like zooids, or both (hence they are trimorphic). Cnidarians' activities are coordinated by a decentralized nerve net and simple receptors. Several free-swimming species of Cubozoa and S ...

Anacropora Spinosa
''Anacropora spinosa'' is a species of briar coral that can be found in the central Indo-Pacific, Southeast Asia, the Solomon Islands, Japan, the East China Sea and the oceanic west Pacific Ocean. It is also found in Rodrigues and the Andaman Islands. It occurs in shallow reefs, from depths of 5–15 m. It is particularly susceptible to coral bleaching, disease and reduction of coral reef habitats. Description ''Anacropora spinosa'' forms bushy clumps of contorted branches up to thick which taper to a point. The corallites are long, crowded and irregular, mostly being untapered. Spines project beneath the corallites. The colour of this coral is usually brownish, and the tips of the branches are often white. Status ''Anacropora spinosa'' is found in shallow reef habitats and is particularly susceptible to coral bleaching and coral disease and is slow to recover. It is an uncommon species and the population is thought to be trending downwards. The International Union fo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

It is very fragile, and is particularly susceptible to coral bleaching Coral bleaching is the process when corals become white due to various stressors, such as changes in temperature, light, or nutrients. Bleaching occurs when coral polyps expel the zooxanthellae (dinoflagellates that are commonly referred to as alg ..., disease and habitat loss.

Anacropora Matthai
''Anacropora matthai'' is a species of briar coral in the family Acroporidae. This species is found in the Central Indo-Pacific in waters off Solomons, Japan, East China Sea, Eastern Australia, Fiji, Palau, and Pohnpei in shallow tropical reef environments, in depths of 8 to 20 meters. The species is named after George Matthai. Description The branches of ''A. matthai'' are 5 millimetres thick, and are straight, with brown and pale brown coloring. Conservation The range of ''A. matthai'' occurs in one protected marine area, but its population is still in decline, so it has been listed as vulnerable by the IUCN Red List.

Pacific Ocean
The Pacific Ocean is the largest and deepest of Earth's five oceanic divisions. It extends from the Arctic Ocean in the north to the Southern Ocean (or, depending on definition, to Antarctica) in the south, and is bounded by the continents of Asia and Oceania in the west and the Americas in the east. At in area (as defined with a southern Antarctic border), this largest division of the World Ocean—and, in turn, the hydrosphere—covers about 46% of Earth's water surface and about 32% of its total surface area, larger than Earth's entire land area combined .Pacific Ocean .
