Acropora Acervata
''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] |
Paleocene
The Paleocene, ( ) or Palaeocene, is a geological epoch (geology), epoch that lasted from about 66 to 56 mya (unit), million years ago (mya). It is the first epoch of the Paleogene Period (geology), Period in the modern Cenozoic Era (geology), Era. The name is a combination of the Ancient Greek ''palaiós'' meaning "old" and the Eocene Epoch (which succeeds the Paleocene), translating to "the old part of the Eocene". The epoch is bracketed by two major events in Earth's history. The K–Pg extinction event, brought on by Chicxulub impact, an asteroid impact and possibly volcanism, marked the beginning of the Paleocene and killed off 75% of living species, most famously the non-avian dinosaurs. The end of the epoch was marked by the Paleocene–Eocene Thermal Maximum (PETM), which was a major climatic event wherein about 2,500–4,500 gigatons of carbon were released into the atmosphere and ocean systems, causing a spike in global temperatures and ocean acidification. In the Pal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cell (biology)
The cell is the basic structural and functional unit of life forms. Every cell consists of a cytoplasm enclosed within a membrane, and contains many biomolecules such as proteins, DNA and RNA, as well as many small molecules of nutrients and metabolites.Cell Movements and the Shaping of the Vertebrate Body in Chapter 21 of Molecular Biology of the Cell '' fourth edition, edited by Bruce Alberts (2002) published by Garland Science. The Alberts text discusses how the "cellular building blocks" move to shape developing embryos. It is also common to describe small molecules such as ...

Acropora Aculeus
''Acropora aculeus'' is a species of acroporid corals found throughout the Indian Ocean, the central Indo-Pacific, Australia, southeast Asia, Japan and the East China Sea. It is also present in the western Pacific Ocean. It is an uncommon species and is particularly prone to coral bleaching, disease, and crown-of-thorns starfish predation; it is also harvested for use in aquaria, and the International Union for Conservation of Nature has assessed it as being a "vulnerable species". Habitat loss is a big concern. Description ''Acropora aculeus'' forms corymbose, pillow-like structures, the horizontal branches being slender and spreading while the upright branches are narrow and shorter. The corallites are distinctive, longer than they are wide, smooth and polished. This coral is usually yellowish or grey, but can be bright bluish-green, and the tips of the branches are often yellow, pale blue, green or brown. It is usually yellow on the Great Barrier Reef and in the Philippines, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Acropora Abrotanoides
''Acropora abrotanoides'' is a species of acroporid coral found in Indo-Pacific waters from the Red Sea and the Gulf of Aden east to the East China Sea, Japan, the central Pacific Ocean and Australia. It is found in shallow coral reefs that are exposed to the action of strong waves, at depths up to 15 m. It is vulnerable to coral bleaching, disease and crown-of-thorns starfish. It is resistant to predation as it has well-developed radial corallite lips. Taxonomy and systematics ''Acropora abrotanoides'' was first described by Lamarck in 1816 as ''Madrepora abrotanoides''. ''Acropora irregularis'' was formerly considered as a separate species, but is now considered as synonymous with ''Acropora abrotanoides''. Description It occurs in colonies of fused branches growing across the seabed (prostrate) with vertical outer branches with diameters of up to ; these can be table-shaped. In the centre of a colony, the branches are fused together—these can be either elongated or co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Acropora Abrolhosensis
''Acropora abrolhosensis'' is a species of acroporid coral that was first described by John Veron in 1985. Found in sheltered lagoons and shallow reefs, it is listed as a vulnerable species on the IUCN Red List. The population of the species is decreasing, and most specimens are found in Western Australia, but occurs in many other areas. It is also listed under CITES Appendix II. Description ''Acropora abrolhosensis'' specimens are found in tree-shaped colonies and are pink, blue, or brown, and the branch tips are pale in colour. These colonies consist of several straight branches, which have large axial corallites (at the end of each branch) and the radial corallites (up the side of each branch) contain circular openings and have swollen ends. The colonies can be over wide and high, and are sometimes compact. Its axial corallites are in diameter. It is similar to '' Acropora copiosa'' and ''Acropora loisetteae''. The species is found at depths of , and is found in enclosed sh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Tegastes Acroporanus
Tegastidae is a family of copepods, which are characterised by having laterally compressed bodies (resembling that of an amphipod), a claw-like mandible in the nauplius stage, and by a modified male genital complex. 85 species have been described in 6 genera. Two species of '' Smacigastes'' are found at hydrothermal vents, while the remaining species are found in shallow water, associated with algae, bryozoans and cnidarians, such as coral Corals are marine invertebrates within the class Anthozoa of the phylum Cnidaria.

Reef Aquarium
A reef aquarium or reef tank is a marine aquarium that prominently displays live corals and other marine invertebrates as well as fish that play a role in maintaining the tropical coral reef environment. A reef aquarium requires appropriately intense lighting, turbulent water movement, and more stable water chemistry than fish-only marine aquaria, and careful consideration is given to which reef animals are appropriate and compatible with each other. Components Reef aquariums consist of a number of components, in addition to the livestock, including: *Display tank: The primary tank in which the livestock are kept and shown. *Stand: A stand allows for placement of the display tank at eye level and provides space for storage of the accessory components. *Sump: An accessory tank in which mechanical equipment is kept. A remote sump allows for a clutter-free display tank. *Refugium: An accessory tank dedicated to the cultivation of beneficial macroalgae and microflora/fauna. The re ...
