Pasilobus Hupingensis
''Pasilobus hupingensis'' is a species of spider in the orb-weaver spider family Araneidae, found in China and Japan. Females of the genus ''Pasilobus'' construct " spanning-thread webs" with only two sectors, making them appear triangular. Widely spaced threads with sticky drops span the three radii of these webs. One end is attached in such a way that it readily breaks free. When a prey item is caught on one of these threads, the line parts at this end and the prey hangs from the web until it is hauled up by the spider. Description Adult females have a total body length of about 8–9 mm. Overall, the body is dark reddish brown, with the carapace and sternum being darker than the abdomen. The carapace is about 3.2–3.4 mm wide and about the same length. The legs are brownish with yellowish brown markings or vice versa. The first leg is longest at about 7.5–8.7 mm in total. The abdomen is about 6.3–6.7 mm long and 13.0–14.4 mm wide with complex ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
