Scolopendridae
Scolopendridae (or, in older documents, Scolopendridæ) is a family of large centipedes ( class Chilopoda). Nearly all species in this family have four ocelli (simple eyes) on each side of the head and only 21 pairs of legs, but there are exceptions: two scolopendrid species feature more legs (''Scolopendropsis bahiensis'', with 21 or 23 leg pairs, and ''S. duplicata'', with 39 or 43 leg pairs), and some scolopendrid species are eyeless and blind (e.g., ''Cormocephalus sagmus'', ''C. pyropygus'', and ''C. delta''). Three Asian members of this family, ''Scolopendra cataracta'', '' Scolopendra paradoxa'', and '' Scolopendra alcyona,'' are known to show amphibious behaviour. Two other species, '' Scolopendra hardwickei'' and ''Hemiscolopendra marginata,'' are known to show sexual dimorphism in the composition of their venom.

Eric Georg Mjöberg (6 August 1882 – 8 July 1938) was a Swedish zoologist and ethnographer who led the first Swedish scientific expeditions to Australia in the early 1900s, and worked in Indonesia.

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of living and fossil organisms as well as viruses. In the hierarchy of biological classification, genus comes above species and below family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. '' Panthera leo'' (lion) and '' Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants of an ancestral taxon are grouped together (i.e. phylogenetic analysis should c ...

Subfamily
In biological classification, a subfamily ( Latin: ', plural ') is an auxiliary (intermediate) taxonomic rank, next below family but more inclusive than genus. Standard nomenclature rules end subfamily botanical names with "-oideae", and zoological names with "-inae". See also * International Code of Nomenclature for algae, fungi, and plants The ''International Code of Nomenclature for algae, fungi, and plants'' (ICN) is the set of rules and recommendations dealing with the formal botanical names that are given to plants, fungi and a few other groups of organisms, all those "trad ... * International Code of Zoological Nomenclature * Rank (botany) * Rank (zoology) Sources {{biology-stub ...

Polyphyly
A polyphyletic group is an assemblage of organisms or other evolving elements that is of mixed evolutionary origin. The term is often applied to groups that share similar features known as homoplasies, which are explained as a result of convergent evolution. The arrangement of the members of a polyphyletic group is called a polyphyly .. ource for pronunciation./ref> It is contrasted with monophyly and paraphyly. For example, the biological characteristic of warm-bloodedness evolved separately in the ancestors of mammals and the ancestors of birds; "warm-blooded animals" is therefore a polyphyletic grouping. Other examples of polyphyletic groups are algae, C4 photosynthetic plants, and edentates. Many taxonomists aim to avoid homoplasies in grouping taxa together, with a goal to identify and eliminate groups that are found to be polyphyletic. This is often the stimulus for major revisions of the classification schemes. Researchers concerned more with ecology than with syst ...

Scolopendra
''Scolopendra'' (through Latin from Greek , ''skolopendra'') is a species-rich genus of large tropical centipedes of the family Scolopendridae. Description The genus ''Scolopendra'' contains many species of centipedes found across the world's tropics and warmer temperate areas. The species vary considerably in coloration and size. ''Scolopendra'' are mostly very large centipedes. The largest species found in tropical climates can exceed and are the largest living centipedes in the world. All ''Scolopendra'' species can deliver a painful bite, injecting venom through their forcipules, which are not fangs or other mouthparts; rather, these are modified legs on the first body segment. Ecology ''Scolopendra'' are active predators, feeding primarily on insects and other invertebrates. Larger specimens have been observed preying on frogs, tarantulas, lizards, birds, snakes, rodents, and even bats. Two southeast Asian species, '' S. cataracta'' and '' S. paradoxa'', are amphibiou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Asanada
''Asanada'' is a genus of centipedes in the subfamily Scolopendrinae. It has thirteen known species, which usually grow between in length. It can be distinguished from the genus '' Cormocephalus'' (= ''Cupipes'') by having smooth (as opposed to punctured) anal pleurae, but is otherwise quite similar in appearance. The type species of the genus is ''A. brevicornis'' (by monotypy In biology, a monotypic taxon is a taxonomic group (taxon) that contains only one immediately subordinate taxon.

Spiracle (arthropods)
A spiracle or stigma is the opening in the exoskeletons of insects and some spiders to allow air to enter the trachea. In the respiratory system of insects, the tracheal tubes primarily deliver oxygen directly into the animals' tissues. The spiracles can be opened and closed in an efficient manner to reduce water loss. This is done by contracting closer muscles surrounding the spiracle. In order to open, the muscle relaxes. The closer muscle is controlled by the central nervous system, but can also react to localized chemical stimuli. Several aquatic insects have similar or alternative closing methods to prevent water from entering the trachea. The timing and duration of spiracle closures can affect the respiratory rates of the organism. Spiracles may also be surrounded by hairs to minimize bulk air movement around the opening, and thus minimize water loss. Although all insects have spiracles, only some spiders have them, such as orb weavers and wolf spiders. Ancestrally, spide ...
