Xanthodaphne Suffusa
''Xanthodaphne suffusa'' is a species of sea snail, a marine gastropod mollusk in the family (biology), family Raphitomidae. Description The length of the shell attains 31.5 mm, its diameter 11.5 mm. (Original description) The small, slender shell is fusiform. The Columella (gastropod), columella is suffused with yellowish pink, the exterior white, with a thin, pale epidermis. The shell contains seven or eight Whorl (mollusc), whorls, without counting the protoconch. The specimen is somewhat eroded on the upper whorls, with indications of a shoulder or carina on the three whorls following the protoconch. The suture is slightly irregular, appressed, distinct, not channeled. The spiral Sculpture (mollusc), sculpture consists of fine threads, alternately larger and smaller, pretty uniform over the whole surface, with narrower interspaces. This sculpture is fainter on the sutural side of the fasciole. The transverse sculpture consists of faint, irregular, sharp edged plications, s ...

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] |
