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 p ...

Lobophylliidae
Lobophylliidae is a Family (biology), family of large polyp Scleractinia, 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 Polyphyly, 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 Morphology (biology), morphological grounds but recent Molecular phylogenetics, molecular analysis has shown that these families are Polyphyly, polyphyletic, the similarities between the species having occurred through convergent evolution. Additionally, some traditional genera such as ''Favia'' and ' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Species
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. It is the basic unit of Taxonomy (biology), classification and a taxonomic rank of an organism, as well as a unit of biodiversity. Other ways of defining species include their karyotype, DNA sequence, morphology (biology), morphology, behaviour, or ecological niche. In addition, palaeontologists 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. About 14% of these had been described by 2011. All species (except viruses) are given a binomial nomenclature, two-part name, a "binomen". The first part of a binomen is the name of a genus to which the species belongs. The second part is called the specific name (zoology), specific name or the specific ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Genus
Genus (; : genera ) is a taxonomic rank above species and below family (taxonomy), family as used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. 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 of an ancestral taxon are grouped together (i.e. Phylogeneti ...

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 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 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 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 corals contain symbiont unicellular organis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Family (biology)
Family (, : ) 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". The delineation of what constitutes a family—or whether a described family should be acknowledged—is established and decided upon by active taxonomists. There are not strict regulations for outlining or acknowledging a family, yet in the realm of plants, these classifications often rely on both the vegetative and reproductive characteristics of plant species. Taxonomists frequently hold varying perspectives on these descriptions, leading to a lack of widespread consensus within the scientific community ...
