Leptopsammia
''Leptopsammia'' is a genus of stony cup corals in the family Dendrophylliidae. Members of this genus are found at depths down to about . They are azooxanthellate, meaning that they do not contain symbiotic photosynthetic algae as do many species of coral. Species The following species are listed in the World Register of Marine Species (WoRMS): *'' Leptopsammia britannica'' (Duncan, 1870) *'' Leptopsammia chevalieri'' Zibrowius, 1980 *'' Leptopsammia columna'' Folkeson, 1919 *'' Leptopsammia crassa'' van der Horst, 1922 *'' Leptopsammia formosa'' (Gravier, 1915) *'' Leptopsammia poculum'' (Alcock, 1902) *''Leptopsammia pruvoti ''Leptopsammia pruvoti'', the sunset cup coral, is a solitary stony coral in the family Dendrophylliidae.

Leptopsammia Pruvoti
''Leptopsammia pruvoti'', the sunset cup coral, is a solitary stony coral in the family Dendrophylliidae. It is an azooxanthellate species, meaning its tissues do not contain the symbiotic unicellular algae (zooxanthellae) of the genus ''Symbiodinium'', as do most corals. It is native to the Mediterranean Sea. The species was described by Henri de Lacaze-Duthiers in 1897 and named to honor the French marine biologist Georges Pruvot. Description ''Leptopsammia pruvoti'' is a solitary stony coral and superficially resembles a sea anemone. The polyp sits in a calcareous cup, wider at the base than the top, which varies in shape from cylindrical and short to conical and long. It grows to a height of about and a diameter of . The polyp is yellow or orange with about ninety-six long, translucent yellow tentacles. It can retract back into the skeletal cup, so that the tentacles become barely visible. This species can be confused with another yellow or orange cup coral, '' Balanophyl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 Genus ( plural genera ) is a taxonomic rank used in the biological classification of living and fossil organisms as well as viruses. In the hierarchy of biological classification, genus comes above species and below family. In binomial ... 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 * ...

Species
In biology, a species is the basic unit of Taxonomy (biology), 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 reproduction, produce Fertility, fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology (biology), 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 binomial nomenclature, 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 specifi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
