Afer Cumingii
''Afer cumingii'' is a species of large sea snail, marine gastropod mollusc in the family (biology), family Tudiclidae. Description The length of the shell attains 65 mm, its diameter 30 mm. (Original description of ''Fusus couderti'' in French) The ventricose shell is whitish, marked with irregular ferruginous-brown spots. It features high, fairly acute Whorl (mollusc), whorls, totaling eight, each elegantly furrowed and presenting a series of depressed tubercles that form a keel-like structure. The oval-rounded Aperture (mollusc), aperture on the right side has crenellations that extend quite far into the interior. The callous Columella (gastropod), columella is furnished at its base with a thick, dentiform fold. The lower end of the shell tapers into a fairly long tail that curves slightly backward at the extremity. Distribution This marine species occurs off Taiwan.https://www.gbif.org/occurrence/search?taxon_key=6125369 Gbif.org: Afer cumingii References * Li ...

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] |
