Tubastraea Faulkneri
''Tubastraea faulkneri'', common name Orange sun coral, is a species of large-polyp stony corals belonging to the family Dendrophylliidae. Other common names of this coral are Orange Cup Coral, Sun Coral, Orange Polyp Coral, Rose Sun Coral, Golden Cup Coral, Sun Flower Coral, and Tube Coral. Etymology The species has been named ''faulkneri'' by the American paleontologist John West Wells in 1982 in honor of Douglas Faulkner, who collected and illustrated in color the specimen used for the description. Distribution This species is mainly present in the Indo-Pacific Ocean, in Australian water and from the Philippines to the Galapagos Islands. Habitat These large-polyp stony corals usually occurs in areas with a strong water flow and a high nutrient content, not necessarily related to the reef, at depths of 3 to 5 m. Description ''Tubastraea faulkneri'' is an encrusting coral that can become massive and strongly convex. The corallites of this species are covered with a porous t ...

Dendrophylliidae
Dendrophylliidae is a family of stony corals. Most (but not all) members are azooxanthellate and thus have to capture food with their tentacles instead of relying on photosynthesis to produce their food. The World Register of Marine Species includes these genera in the family: * '' Astroides'' Quoy & Gaimard, 1827 * ''Balanophyllia'' Wood, 1844 * '' Balanopsammia'' Ocana & Brito, 2013 * '' Bathypsammia'' Marenzeller, 1907 * '' Cladopsammia'' Lacaze-Duthiers, 1897 * '' Dendrophyllia'' de Blainville, 1830 * '' Dichopsammia'' Song, 1994 * '' Duncanopsammia'' Wells, 1936 * '' Eguchipsammia'' Cairns, 1994 * ''Enallopsammia'' Sismonda, 1871 * '' Endopachys'' Milne Edwards & Haime, 1848 * '' Endopsammia'' Milne Edwards & Haime, 1848 * ''Heteropsammia ''Heteropsammia'' is a genus of apozooxanthellate corals that belong to the family Dendrophylliidae. Anatomy These corals consist of free-living, single polyps, of a diameter of around 2.5 cm. They form a symbiotic relationship w ...

Indo-Pacific Ocean
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 all ...

Corallite
A corallite is the skeletal cup, formed by an individual stony coral polyp, in which the polyp sits and into which it can retract. The cup is composed of aragonite, a crystalline form of calcium carbonate, and is secreted by the polyp. Corallites vary in size, but in most colonial corals they are less than in diameter. The inner surface of the corallite is known as the calyx. The vertical blades inside the calyx are known as septa and in some species, these ridges continue outside the corallite wall as costae. Where there is no corallite wall, the blades are known as septocostae. The septa, costae and septocostae may have ornamentation in the form of teeth and may be thick, thin or variable in size. Sometimes there are paliform lobes, in the form of rods or blades, rising from the inner margins of the septa. These may form a neat circle called the paliform crown. The septa do not usually unite in the centre of the corallite, instead they form a columella, a tangled mass of int ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coenosteum
In corals, the coenosteum is the stony skeletal material secreted by the coenosarc, the layer of living material lying between the corallites (the stony cups in which the polyps sit). The coenosteum is composed of aragonite Aragonite is a carbonate mineral, one of the three most common naturally occurring crystal forms of calcium carbonate, (the other forms being the minerals calcite and vaterite). It is formed by biological and physical processes, including prec ..., a crystalline form of calcium carbonate, and is generally a spongy, porous material. Sometimes the coenosteum has ornamentation such as ridges and beads, visible as raised areas of the coenosarc. The coenosteum and corallites together are known as the corallum.

Tubastraea Coccinea
Orange cup coral (''Tubastraea coccinea'') belongs to a group of corals known as large-polyp stony corals. This non-reef building coral extends beautiful translucent tentacles at night. ''Tubastraea coccinea'' is heterotrophic and does not contain zooxanthellae in its tissues as many tropical corals do, allowing it to grow in complete darkness as long as it can capture enough food. Habitat ''Tubastraea coccinea'' inhabits shaded vertical surfaces and caverns down to huge depths. Orange-cup-corals are also found in very cold water throughout the world. Orange-cup corals often dominate tropical habitats not occupied by other coral species, such as wrecks and cryptic reef habitats. They also colonize artificial structures, but experiments have demonstrated similar preferences for granite, cement, steel and tile. In Brazil, they are most abundant in the shallow sub-tidal zone at shallow depths between 0m and 3m.De Paula & Creed, 2004, 2005, Creed 2006 Invasive introduction and ran ...

Ahermatypic
Hermatypic corals are those corals in the order Scleractinia which build reefs by depositing hard calcareous material for their skeletons, forming the stony framework of the reef. Corals that do not contribute to coral reef development are referred to as ahermatypic (non-reef-building) species. Many reef-forming corals contain symbiotic Symbiosis (from Greek , , "living together", from , , "together", and , bíōsis, "living") is any type of a close and long-term biological interaction between two different biological organisms, be it mutualistic, commensalistic, or parasit ... photosynthetic zooxanthellae, which contribute to their nutritional needs. The term "hermatypic" is sometimes misused, being assumed to apply to all zooxanthellate corals. However, there are zooxanthellae in many non reef-forming corals; and not all hermatypic corals in shallow water contain zooxanthellae. Further, some hermatypic corals live at depths to which light cannot penetrate; they form ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Zooxanthellae
Zooxanthellae is a colloquial term for single-celled dinoflagellates that are able to live in symbiosis with diverse marine invertebrates including demosponges, corals, jellyfish, and nudibranchs. Most known zooxanthellae are in the genus ''Symbiodinium'', but some are known from the genus '' Amphidinium'', and other taxa, as yet unidentified, may have similar endosymbiont affinities. The true ''Zooxanthella'' K.brandt is a mutualist of the radiolarian ''Collozoum inerme'' (Joh.Müll., 1856) and systematically placed in Peridiniales. Another group of unicellular eukaryotes that partake in similar endosymbiotic relationships in both marine and freshwater habitats are green algae zoochlorellae. Zooxanthellae are photosynthetic organisms, which contain chlorophyll a and chlorophyll c, as well as the dinoflagellate pigments peridinin and diadinoxanthin. These provide the yellowish and brownish colours typical of many of the host species. During the day, they provide their host ...

Coral
Corals are marine invertebrates within the class Anthozoa of the phylum Cnidaria. They typically form compact colonies of many identical individual polyps. Coral species include the important reef builders that inhabit tropical oceans and secrete calcium carbonate to form a hard skeleton. A coral "group" is a colony of very many genetically identical polyps. Each polyp is a sac-like animal typically only a few millimeters in diameter and a few centimeters in height. A set of tentacles surround a central mouth opening. Each polyp excretes an exoskeleton near the base. Over many generations, the colony thus creates a skeleton characteristic of the species which can measure up to several meters in size. Individual colonies grow by asexual reproduction of polyps. Corals also breed sexually by spawning: polyps of the same species release gametes simultaneously overnight, often around a full moon. Fertilized eggs form planulae, a mobile early form of the coral polyp which, when m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hermaphrodite
In reproductive biology, a hermaphrodite () is an organism that has both kinds of reproductive organs and can produce both gametes associated with male and female sexes. Many Taxonomy (biology), taxonomic groups of animals (mostly invertebrates) do not have separate sexes. In these groups, hermaphroditism is a normal condition, enabling a form of sexual reproduction in which either partner can act as the female or male. For example, the great majority of tunicata, tunicates, pulmonate molluscs, opisthobranch, earthworms, and slugs are hermaphrodites. Hermaphroditism is also found in some fish species and to a lesser degree in other vertebrates. Most plants are also hermaphrodites. Animal species having different sexes, male and female, are called Gonochorism, gonochoric, which is the opposite of hermaphrodite. There are also species where hermaphrodites exist alongside males (called androdioecy) or alongside females (called gynodioecy), or all three exist in the same species ( ...
