IUCN Red List
The International Union for Conservation of Nature (IUCN) Red List of Threatened Species, also known as the IUCN Red List or Red Data Book, founded in 1964, is the world's most comprehensive inventory of the global conservation status of biological species. It uses a set of precise criteria to evaluate the extinction risk of thousands of species and subspecies. These criteria are relevant to all species and all regions of the world. With its strong scientific base, the IUCN Red List is recognized as the most authoritative guide to the status of biological diversity. A series of Regional Red Lists are produced by countries or organizations, which assess the risk of extinction to species within a political management unit. The aim of the IUCN Red List is to convey the urgency of conservation issues to the public and policy makers, as well as help the international community to reduce species extinction. According to IUCN the formally stated goals of the Red List are to provi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Acropora Akajimensis
''Acropora donei'' is a species of acroporid coral that was first described by J. Veron and Carden Wallace in 1984. Found in fringing reefs and the upper slopes of shallow reefs, it occurs at depths of . The species is rated as vulnerable on the IUCN Red List, with a decreasing population, and is affected by disease. It is not common but found over a large area, and is listed under CITES Appendix II. Description ''Acropora donei'' forms in colonies with a width of up to , and are made of many fused branches. It is cream, white, green, and sometimes pale brown in colour. The branches are flat, but towards the centre, the ends are upward-facing. The ends of all branches are blunt but neat, and flaring lips are present on larger radial corallites (on the sides of branches), while the smaller corallites lack these. Its coenosteum is bristly, making the species appear rough, and there are no similar species within genus ''Acropora''. It occurs in tropical, shallow reefs; typically in ...

Acropora Forskali
''Acropora'' is a genus of small polyp stony coral in the phylum Cnidaria. 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. Anatomy and distribution Depending on the species and location, ''Acropora'' species may grow as plates or slender or broad branches. Like other corals, ''Acropora'' corals are colonies of individual polyps, which are about 2 mm across and share tissue and a nerve net. The polyps can withdraw back into the coral in response to movement or disturbance by potential predators, but when undisturbed, they protrude slightly. The polyps typically extend further at night to help capture plankton and organic matter from the water. The species are distributed in the Indo-Pacific (over 100 species) and Caribbean (3 species).

Acropora Efflorescens
''Acropora cytherea'' is a stony coral which forms horizontal table like structures. It occurs in the Indo-Pacific Ocean in areas with little wave action, favouring back reef environments from depth. Description ''Acropora cytherea'' is a colonial species of coral that grows in large horizontal plates. These are formed of many tiny branchlets growing vertically or at an angle and others growing horizontally to extend the colony. They may branch and link together and near the centre the plates may become a solid mass of joined branchlets. The surface of the coral is covered by a thin layer of living tissue. This has a rough surface and contains ''zooxanthella'', symbiotic, unicellular, photosynthetic algae. These give the coral its cream or pale brown colour (occasionally pale blue). The calcium carbonate skeleton is secreted by many small polyps which are joined together through an interconnecting network of channels inside the skeleton. At night, and sometimes during the day, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Acropora Copiosa
''Acropora muricata'', commonly called staghorn coral, is a species of acroporid coral found in the Gulf of Aden, the Red Sea, Indian Ocean, Persian Gulf, Australia, central Indo-Pacific, Japan, Southeast Asia, the East China Sea and the oceanic central and western Pacific Ocean. It is found in tropical shallow reefs, slopes of reefs, and in lagoons, from depths of 5 to 30 m. It was described by Dana in 1846. Description It occurs in arborescent colonies forming thickets with diameters of up to . Its branches vary from being short in shallower water to being less clumped in deeper water. Its axial corallites protrude from the branches and the radial corallites are tube-shaped. It is blue, brown or cream, and the ends of branches are pale. It looks similar to '' Acropora teres''.

Acropora Cophodactyla
''Acropora cophodactyla'' is a species of uncertain validity (taxon inquirendum) of acroporid coral found in the central Indo-Pacific, Australia, southeast Asia, the Solomon Islands and the western Pacific Ocean. It is also found in Fiji, Andaman Islands and American Samoa. It may be synonymous with '' A. humilis''. It is found in shallow tropical coral reefs on exposed upper slopes and flats, at depths of 0 to 12 m. It was described by Brook in 1892. Description ''Acropora cophodactyla'' occurs in encrusted-based colonies composed of digitated bushes. Its colonies contain thick branches that taper to a point, at which a single obvious axial corallite is located. Incipient axial and radial corallites are of varying diameters and occur in no specific pattern. The species is mainly purple or blue in colour. It looks similar to ''Acropora anthocercis'', ''Acropora appressa'', and ''Acropora humilis. Distribution It is listed as a data deficient species on the IUCN Red List ...

Acropora Convexa
''Acropora millepora'' is a species of branching stony coral native to the western Indo-Pacific where it is found in shallow water from the east coast of Africa to the coasts of Japan and Australia. It was first described in 1834 by Christian Gottfried Ehrenberg as ''Heteropora millepora''. Description ''Acropora millepora'' is a small colonial coral that grows in clumps. The short branches are cylindrical. The radial corallites are all the same size and have projecting lower rims, giving them a scale-like appearance. The colour is variable and may be green with orange tipped branches, or pale pink, orange, plain green or blue. Distribution and habitat ''Acropora millepora'' is a common species and is found in the western and central Indo-Pacific. Its range extends from the Red Sea, Kenya and South Africa to India, Malaysia, Japan, Indonesia and Australia. This coral grows in shallow water, between two and twelve metres (six and forty feet) deep, mostly on reef flats, but also o ...
