Homophyllia Australis
''Homophyllia'' is a genus of stony corals in the family Lobophylliidae Lobophylliidae is a family of large polyp stony corals. The family was created in 2009 after a revision of the "robust" families of Faviidae, Merulinidae, Mussidae and Pectiniidae, which had been shown to be polyphyletic. The family Lobophylliida ....

Species
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specific name or the specific epithet (in botanical nomenclature, also sometimes i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants ...

Scleractinia
Scleractinia, also called stony corals or hard corals, are marine animals in the phylum Cnidaria that build themselves a hard skeleton. The individual animals are known as polyp (zoology), polyps and have a cylindrical body crowned by an oral disc in which a mouth is fringed with tentacles. Although some species are solitary, most are Colony (biology), colonial. The founding polyp settles and starts to secrete calcium carbonate to protect its soft body. Solitary corals can be as much as across but in colonial species the polyps are usually only a few millimetres in diameter. These polyps reproduce asexually by budding, but remain attached to each other, forming a multi-polyp colony of cloning, clones with a common skeleton, which may be up to several metres in diameter or height according to species. The shape and appearance of each coral colony depends not only on the species, but also on its location, depth, the amount of water movement and other factors. Many shallow-water co ...

Family (biology)
Family ( la, familia, plural ') is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as the "walnut family". What belongs to a family—or if a described family should be recognized at all—are proposed and determined by practicing taxonomists. There are no hard rules for describing or recognizing a family, but in plants, they can be characterized on the basis of both vegetative and reproductive features of plant species. Taxonomists often take different positions about descriptions, and there may be no broad consensus across the scientific community for some time. The publishing of new data and opini ...

Lobophylliidae
Lobophylliidae is a family of large polyp stony corals. The family was created in 2009 after a revision of the "robust" families of Faviidae, Merulinidae, Mussidae and Pectiniidae, which had been shown to be polyphyletic. The family Lobophylliidae was formed out of the Indo-Pacific species that had traditionally been included in Mussidae, and some of the species which had previously formed Pectiniidae, the remaining species from Pectiniidae having been merged into Merulinidae. The type genus is '' Lobophyllia''. Taxonomy The "robust" stony coral families of Faviidae, Merulinidae, Mussidae and Pectiniidae, have traditionally been recognised on morphological grounds but recent molecular analysis has shown that these families are polyphyletic, the similarities between the species having occurred through convergent evolution. Additionally, some traditional genera such as ''Favia'' and '' Scolymia'' have been found to be polyphyletic, with the Atlantic faviids and scolymids being mor ...

Homophyllia Bowerbanki
''Homophyllia bowerbanki'' is a vulnerable species of coral found in the Pacific and Indian Oceans. This species is moderately common, but it is threatened by crown-of-thorns starfish predation and habitat loss. Description ''Homophyllia bowerbanki'' is a small, encrusting coral but occasionally reach a diameter of over . The corallites are cerioid and have irregular shapes, and there is usually an obvious central one. The colour is often mottled and is generally reddish-brown, brown or grey. The corallites are irregularly shaped and may be arranged singly or in short valleys with continuous walls containing several corallites. The polyps are still fleshy when retracted. Distribution It is found in the Pacific and Indian Oceans from Australia to Japan and Kiribati. Biology ''Homophyllia bowerbanki'' is a zooxanthellate species of coral. It obtains most of its nutritional needs from the symbiotic dinoflagellates that live inside its soft tissues. These photosynthetic organisms pr ...
