Polyzoniida
__NOTOC__ Polyzoniida is an order of millipedes in the subterclass Colobognatha containing three families and at least 74 described species. Description Polyzoniidans have a somewhat domed dorsal surface with a flat ventral side. Their heads are small and cone-like, with few ocelli. They lack a dorsal groove and paranota (lateral extensions of each segment). Classification The order Polyzoniida contains three families: :Hirudisomatidae Silvestri, 1896 (6 genera, 20 species) :Polyzoniidae Newport, 1844 (6 genera, 22 species) :Siphonotidae Cook, 1895 (15 genera, 40 species) Distribution The family Hirudisomatidae occurs from Spain to the Himalayas in Eurasia, Japan, and in North America from southwest Canada to central Mexico. Polyzoniidae has a holarctic (northern hemisphere) distribution, occurring in the northwest and northeast United States, eastern Canada, and in Europe from the United Kingdom and France to Siberia Siberia ( ; rus, Сибирь, r=Sibir', p=sʲɪˈbʲ ...

Millipede
Millipedes are a group of arthropods that are characterised by having two pairs of jointed legs on most body segments; they are known scientifically as the class Diplopoda, the name derived from this feature. Each double-legged segment is a result of two single segments fused together. Most millipedes have very elongated cylindrical or flattened bodies with more than 20 segments, while pill millipedes are shorter and can roll into a tight ball. Although the name "millipede" derives from the Latin for "thousand feet", no species was known to have 1,000 or more until the discovery of '' Eumillipes persephone'', which can have over 1,300 legs. There are approximately 12,000 named species classified into 16 orders and around 140 families, making Diplopoda the largest class of myriapods, an arthropod group which also includes centipedes and other multi-legged creatures. Most millipedes are slow-moving detritivores, eating decaying leaves and other dead plant matter. Some eat fu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Colobognatha
Colobognatha is a clade (formally considered a subterclass) of helminthomorph millipedes containing four orders: Platydesmida, Polyzoniida, Siphonocryptida, and Siphonophorida. Description The Colobognatha are united by several shared traits (synapomorphies). Males have two pairs of simple, leg-like gonopods, consisting of the rear leg pair of body segment 7 and the foreword-most leg pair of segment 8. They possess tubular defensive glands that open on the sides of the body, and lack a palp-like structure on their gnathochilaria. Other traits found in colobognathans, but not exclusively, include a distinctly narrow head, lack of Tömösváry organs, and no more than two pairs of ocelli A simple eye (sometimes called a pigment pit) refers to a form of eye or an optical arrangement composed of a single lens and without an elaborate retina such as occurs in most vertebrates. In this sense "simple eye" is distinct from a multi-le .... References {{Taxonbar, from=Q169808 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Class (biology)
In biological classification, class ( la, classis) is a taxonomic rank, as well as a taxonomic unit, a taxon, in that rank. It is a group of related taxonomic orders. Other well-known ranks in descending order of size are life, domain, kingdom, phylum, order, family, genus, and species, with class fitting between phylum and order. History The class as a distinct rank of biological classification having its own distinctive name (and not just called a ''top-level genus'' ''(genus summum)'') was first introduced by the French botanist Joseph Pitton de Tournefort in his classification of plants that appeared in his ''Eléments de botanique'', 1694. Insofar as a general definition of a class is available, it has historically been conceived as embracing taxa that combine a distinct ''grade'' of organization—i.e. a 'level of complexity', measured in terms of how differentiated their organ systems are into distinct regions or sub-organs—with a distinct ''type'' of construc ...

Orator F
An orator, or oratist, is a public speaker, especially one who is eloquent or skilled. Etymology Recorded in English c. 1374, with a meaning of "one who pleads or argues for a cause", from Anglo-French ''oratour'', Old French ''orateur'' (14th century), Latin ''orator'' ("speaker"), from ''orare'' ("speak before a court or assembly; plead"), derived from a Proto-Indo-European base *''or-'' ("to pronounce a ritual formula"). The modern meaning of the word, "public speaker", is attested from c. 1430. History In ancient Rome, the art of speaking in public (''Ars Oratoria'') was a professional competence especially cultivated by politicians and lawyers. As the Greeks were still seen as the masters in this field, as in philosophy and most sciences, the leading Roman families often either sent their sons to study these things under a famous master in Greece (as was the case with the young Julius Caesar), or engaged a Greek teacher (under pay or as a slave). In the young revolution ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ocelli
A simple eye (sometimes called a pigment pit) refers to a form of eye or an optical arrangement composed of a single lens and without an elaborate retina such as occurs in most vertebrates. In this sense "simple eye" is distinct from a multi-lensed "compound eye", and is not necessarily at all simple in the usual sense of the word. The structure of an animal's eye is determined by the environment in which it lives, and the behavioural tasks it must fulfill to survive. Arthropods differ widely in the habitats in which they live, as well as their visual requirements for finding food or conspecifics, and avoiding predators. Consequently, an enormous variety of eye types are found in arthropods. They possess a wide variety of novel solutions to overcome visual problems or limitations. Use of the term ''simple eye'' is flexible, and must be interpreted in proper context; for example, the eyes of humans and of other large animals such as most cephalopods, are '' camera eyes'' and ...
