Barychelidae
Barychelidae, also known as brushed trapdoor spiders, is a spider family with about 300 species in 42 genera. Most spiders in this family build trapdoor burrows. For example, the long '' Sipalolasma'' builds its burrow in rotted wood, with a hinged trapdoor at each end. The long ''Idioctis'' builds its burrow approximately deep, just below the high tide level, sealing the opening with a thin trapdoor. Some species avoid flooding by plugging their burrows, while others can avoid drowning by trapping air bubbles within the hairs covering their bodies. Some members of this group have a rake on the front surface of their chelicerae used for compacting burrow walls. These spiders can run up glass like tarantulas, and some can stridulate, though it isn't audible to humans. Distribution Barychelids are found in Australia, New Caledonia, South America, Africa, Madagascar, India, New Guinea, and Pacific islands. Genera , the World Spider Catalog accepts the following genera: *'' Am ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Species
In biology, a species is the basic unit of Taxonomy (biology), 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 reproduction, produce Fertility, fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology (biology), 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 binomial nomenclature, 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 specifi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Anton Ausserer
Anton Ausserer (5 July 184320 July 1889)Maurer, Ferdinand: ''Nachruf an Dr. Anton Ausserer.'' Programm des kk. acad. Gymnasiums in Grätz. Graz 1890 was an Austrian naturalist specialising in spiders.Bonnet, Pierre: Bibliographia aranearum, Les frères Doularoude. Toulouse 1945 His father died when he was a youth, and he and his family suffered much economic hardship, but he was supported and encouraged by Camill Heller, professor of Zoology and Comparative Anatomy at the University of Innsbruck. Life and career Anton Ausserer was one of five children of a gunsmith in Bozen (Bolzano), Tyrol). His teachers noticed his talent at a young age, so they encouraged his father to send him to the Franciscan high school. There he had Vincenz Maria Gredler, a pioneer of zoological research in Tyrol, as his teacher. Already at this time he showed a great interest in science. At the age of 15 he became an orphan. During high school and university he had to struggle with bitter economic hard ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mygalomorphae Genera
The Mygalomorphae, or mygalomorphs, are an infraorder of spiders, and comprise one of three major groups of living spiders with over 3000 species, found on all continents except Antarctica. Many members are known as trapdoor spiders due to them forming trapdoors over their burrows. Other prominent groups include Australian funnel web spiders and tarantulas, with the latter accounting for around one third of all mygalomorphs. Description This group of spiders comprises mostly heavy-bodied, stout-legged spiders including tarantulas, Australian funnel-web spiders, mouse spiders, and various families of spiders commonly called trapdoor spiders. Like the "primitive" suborder of spiders Mesothelae, they have two pairs of book lungs, and downward-pointing chelicerae. Because of this, the two groups were once believed to be closely related. Later it was realized that the common ancestors of all spiders had these features (a state known as symplesiomorphy). Following the br ...
