Solariella Delicata
''Solariella delicatus'' is a species of sea snail, a marine (ocean), marine gastropod mollusk in the family (biology), family Solariellidae.Bouchet, P. (2013). Machaeroplax delicatus (Dall, 1919). Accessed through: World Register of Marine Species at http://www.marinespecies.org/aphia.php?p=taxdetails&id=740727 on 2013-11-22 Description (Original description by W.H. Dall) The height of the shell attains 7 mm, its diameter 6.5 mm. The small, white shell has about four well rounded Whorl (mollusc), whorls exclusive of the rather promment minute glassy nucleus. The Suture (anatomy), suture is distinct, almost appressed. The spiral Sculpture (mollusc), sculpture shows a prominent thread at the shoulder, two with an intercala smaller thread at the verge of the Umbilicus (mollusc), umbilicus and numerous feeble minute elevated lines under-running the axial sculpture. The Umbilicus (mollusc), umbilicus is narrow and deep. The axial sculpture consists of very numerous, equal, r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
