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] |
Spider
Spiders (order Araneae) are air-breathing arthropods that have eight legs, chelicerae with fangs generally able to inject venom, and spinnerets that extrude silk. They are the largest order of arachnids and rank seventh in total species diversity among all orders of organisms. Spiders are found worldwide on every continent except for Antarctica, and have become established in nearly every land habitat. , 50,356 spider species in 132 families have been recorded by taxonomists. However, there has been debate among scientists about how families should be classified, with over 20 different classifications proposed since 1900. Anatomically, spiders (as with all arachnids) differ from other arthropods in that the usual body segments are fused into two tagmata, the cephalothorax or prosoma, and the opisthosoma, or abdomen, and joined by a small, cylindrical pedicel, however, as there is currently neither paleontological nor embryological evidence that spiders ever had a sep ...

Dysdera
''Dysdera'' is a genus of woodlouse hunting spiders that was first described by Pierre André Latreille in 1804. They originated from Central Asia to Central Europe. The family has gained many common names from their individual species, including the "European garden spider", the "slater-eating spider", the "sow-bug killer", the "woodlouse hunter", and the "woodlouse spider". A bite from one of these spiders can be painful due to their large fangs and wide jaw. It may leave an itchy, swollen, or red bump, but the venom from one of their bites is not harmful to humans. Description Adults have a reddish-brown body and legs, and can grow up to long. Females are generally larger growing from , while males are about . Their six eyes are close together in an oval shape, and they have eight reddish legs, the second pair facing backward. ''Dysdera'' live in natural shelters, which they wrap by totally white silk. The inhabitants of hot and humid forest will take any potential shelt ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dysderidae
Dysderidae, also known as woodlouse hunters, sowbug-eating spiders, and cell spiders, is a family of araneomorph spiders first described by Carl Ludwig Koch in 1837. They are found primarily in Eurasia, extending into North Africa with very few species occurring in South America. '' Dysdera crocata'' is introduced into many regions of the world. Dysderids have six eyes, and are haplogyne, i.e. the females lack a sclerotized epigyne. There is a substantial number of genera, but two of them, ''Dysdera'' and ''Harpactea'', account for a very large number of the species and are widespread across the family's range. One species, ''Dysdera crocata'' (the woodlouse hunter), has been transported over much of the planet together with its preferred foods— woodlice. ''Dysdera'' also feeds on beetles. These spiders have very large chelicerae, which they use to pierce the armored bodies of woodlice and beetles. There are also some reports that they have a mildly toxic venom that ca ...

Subspecies
In biological classification, subspecies is a rank below species, used for populations that live in different areas and vary in size, shape, or other physical characteristics ( morphology), but that can successfully interbreed. Not all species have subspecies, but for those that do there must be at least two. Subspecies is abbreviated subsp. or ssp. and the singular and plural forms are the same ("the subspecies is" or "the subspecies are"). In zoology, under the International Code of Zoological Nomenclature, the subspecies is the only taxonomic rank below that of species that can receive a name. In botany and mycology, under the International Code of Nomenclature for algae, fungi, and plants, other infraspecific ranks, such as variety, may be named. In bacteriology and virology, under standard bacterial nomenclature and virus nomenclature, there are recommendations but not strict requirements for recognizing other important infraspecific ranks. A taxonomist decides w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
World Spider Catalog
The World Spider Catalog (WSC) is an online searchable database concerned with spider taxonomy. It aims to list all accepted families, genera and species, as well as provide access to the related taxonomic literature. The WSC began as a series of individual web pages in 2000, created by Norman I. Platnick Norman Ira Platnick (December 30, 1951 – April 8, 2020) was an American biological systematist and arachnologist. At the time of his death, he was a professor emeritus of the Richard Gilder Graduate School and Peter J. Solomon Family Curator Em ... of the American Museum of Natural History. After Platnick's retirement in 2014, the Natural History Museum of Bern (Switzerland) took over the catalog, converting it to a relational database. , 50,151 accepted species were listed. The order Araneae (spiders) has the seventh-most species of all orders. The existence of the World Spider Catalog makes spiders the largest taxon with an online listing that is updated regularly.
