Stylophora Madagascarensis
''Stylophora madagascarensis'' is a species of stony coral in the family Pocilloporidae. It is native to the tropical western Indian Ocean where it is confined to the coasts of Madagascar, growing in shallow water. Description ''Stylophora madagascarensis'' is a colonial species of coral forming clumps of slender, compact branches with blunt ends. The branches are up to in diameter. The corallites (stony cups in which the polyps sit) are crowded and circular, with those near the tips of the branches often being hooded. The corallites have six septa (stony plates forming the wall of the corallite) fused to a central, style-like columella. The coenosteum (the coral's stony skeleton) is covered with tiny spines. This is a zooxanthellate species of coral, the tissues of which harbour single-celled dinoflagellates living in symbiosis Symbiosis (from Greek , , "living together", from , , "together", and , bíōsis, "living") is any type of a close and long-term biologica ...

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] |
