Acropora Desalwii
''Acropora desalwii'' is a species of acroporid coral that was first described by Dr Carden Wallace in 1994. Found in sheltered, tropical, shallow reefs, mainly on the slopes, this species is generally found at depths below , but this can be as low as . The species is rated as vulnerable on the IUCN Red List, with a decreasing population, and is affected by disease. It is common and found over a large area, and is listed under CITES Appendix II. Description ''Acropora desalwii'' forms in corymbose colonies consisting of crowded branches. The branchlets at the edge of the corymbose colonies are obvious, upward-facing, and can have over a single axial corallite, which are tube-shaped and long, and facing upwards. It is green, brown or blue in colour, and radial corallites are also present on the sides of the branchlets. It resembles ''Acropora parapharaonis'' and '' Acropora willisae''. It exists in a marine environment in tropical, shallow, sheltered reefs, generally at depths ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carden Wallace
Carden Crea Wallace ( fl. 1970–) is an Australian scientist who was the curator/director of the Museum of Tropical Queensland from 1987 to 2003. She is an expert on corals having written a "revision of the Genus ''Acropora''". Wallace was part of a team that discovered mass spawning of coral in 1984. Life Carden C. Wallace graduated with a first class degree in Science from the University of Queensland in 1970. She gave birth to two sons in the 1970s. From 1970 to 1976, she was the curator of lower vertebrates at the Queensland Museum. She obtained her Ph.D. in 1979 at the University of Queensland. Wallace spent a brief period researching at the Australian Institute of Marine Science before researching Marine Biology from 1980 as a fellow at the James Cook University of North Queensland. In 1984, Wallace and six others first reported that corals took part in mass spawning which they observed on the Great Barrier Reef in October/November. Since they first observed reprodu ...

Vulnerable Species
A vulnerable species is a species which has been Conservation status, categorized by the International Union for Conservation of Nature as being threatened species, threatened with extinction unless the circumstances that are threatened species, threatening its survival and reproduction improve. Vulnerability is mainly caused by habitat loss or destruction of the species' home. Vulnerable habitat or species are monitored and can become increasingly threatened. Some species listed as "vulnerable" may be common in captivity (animal), captivity, an example being the military macaw. There are currently 5196 animals and 6789 plants classified as Vulnerable, compared with 1998 levels of 2815 and 3222, respectively. Practices such as cryoconservation of animal genetic resources have been enforced in efforts to conserve vulnerable breeds of livestock specifically. Criteria The International Union for Conservation of Nature uses several criteria to enter species in this category. A tax ...

Fauna Of Southeast Asia
Southeast Asia, also spelled South East Asia and South-East Asia, and also known as Southeastern Asia, South-eastern Asia or SEA, is the geographical south-eastern region of Asia, consisting of the regions that are situated south of mainland China, east of the Indian subcontinent, and north-west of mainland Australia. Southeast Asia is bordered to the north by East Asia, to the west by South Asia and the Bay of Bengal, to the east by Oceania and the Pacific Ocean, and to the south by Australia and the Indian Ocean. Apart from the British Indian Ocean Territory and two out of 26 atolls of Maldives in South Asia, Maritime Southeast Asia is the only other subregion of Asia that lies partly within the Southern Hemisphere. Mainland Southeast Asia is completely in the Northern Hemisphere. East Timor and the southern portion of Indonesia are the only parts that are south of the Equator. The region lies near the intersection of geological plates, with both heavy seismic and volcani ... [...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 ...

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 ...

Acropora
''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). ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Indo-Pacific
The Indo-Pacific is a vast biogeographic region of Earth. In a narrow sense, sometimes known as the Indo-West Pacific or Indo-Pacific Asia, it comprises the tropical waters of the Indian Ocean, the western and central Pacific Ocean, and the seas connecting the two in the general area of Indonesia. It does not include the temperate and polar regions of the Indian and Pacific oceans, nor the Tropical Eastern Pacific, along the Pacific coast of the Americas, which is also a distinct marine realm. The term is especially useful in marine biology, ichthyology, and similar fields, since many marine habitats are continuously connected from Madagascar to Japan and Oceania, and a number of species occur over that range, but are not found in the Atlantic Ocean. The region has an exceptionally high species richness, with the world's highest species richness being found in at its heart in the Coral Triangle, and a remarkable gradient of decreasing species richness radiating outward in al ...

Acroporidae
Acroporidae is a family of small polyped stony corals in the phylum Cnidaria. The name is derived from the Greek ''"akron"'' meaning "summit" and refers to the presence of a corallite at the tip of each branch of coral. They are commonly known as staghorn corals and are grown in aquaria by reef hobbyists. Description Staghorn corals are the dominant group of reef builders. They come in many shapes and sizes and can be highly variable in colour and form, even within the same species. Most are either a branching variant or a wall/ table top variant shaped and some are encrusting. Encrusting means they grow over rock structure. the Their colours vary between browns, whites, pinks, blues, yellows, greens and purple, depending not only on species but also on the growing conditions. Identification is difficult and requires close examination of the corallites and a biochemical and genetic analysis. There is a corallite at the tip of each branch and, with the exception of ''Astreopora ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
