The dorsal surface has an homogeneously dark-grey to black color with a white median longitudinal stripe of about 8 to 12% of the body width. The ventral side is white to light-grey, usually with a median longitudinal light-grey stripe. The numerous eyes are distributed in a single row along the body margins in the first millimetres and posteriorly spread to the dorsum, usually occupying up to 30% of the body width on each side, but some eyes can be close to the median line.

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] |
