Morula Lepida
''Morula lepida'' (from Latin ''lepida'': elegant, fine) is a species of sea snail, a marine gastropod mollusk in the family (biology), family Muricidae, the murex snails or rock snails. Description The squamous shell is medium sized for the genus, attaining a length of up to 15 mm at maturity. The Spire (mollusc), spire sits high with 2.5+ partly broken protoconch whorls. The teleoconch has up to 6 elongated whorls and impressed sutures. The protoconch is smooth and conical. The axial sculpture consists of moderately high, rounded ribs with about 8-9 on the first and fourth teleoconch whorls, 8 on the second and third whorls and 9-11 on the fifth and sixth whorls. The spiral sculpture consists of numerous, narrow, squamous cords of about the same size. The last teleoconch whorls has 26-28 such cords with 2 or 3 on its abapical part being slightly larger. The aperture is ovate with a fully adherent columellar lip that is smooth apart from 2 or 3 small abapical nodules. The ana ...

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] |
