Broderipia Rosea
''Broderipia rosea'' is a species of sea snail, a marine gastropod mollusk in the family Trochidae, the top snails. Description The height of the shell attains 4⅓ mm, its diameter 2½ mm. The shell is limpet-like, but with a recurved beak projecting beyond the posterior outline of the aperture. The shell is very convex, sloping convexly toward the front margin. The surface of the shell is lusterless, showing under a lens rather rude concentric growth lines, and very numerous, close, fine striae, radiating from the apex to the margins. The coloration consists of narrow red stripes obliquely descending from the median line to the borders, forming a series of V-shaped markings. The beak is rolled forward and a trifle inclined laterally, but the (dextral) apical whorl is lost. The aperture is oval. Its posterior margin is scarcely expanded. Its cavity is deep, scarcely perceptibly and nacreous. Distribution This species occurs in the Red Sea, the Indian Ocean and in the Pac ...

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] |
