Euathlus Affinis
''Euathlus affinis'' is a species of spider belonging to the family Theraphosidae (tarantulas). It is native to Chile. Taxonomy The species was first described in 1849 as ''Mygale affinis''. However, ''Mygale'' had been used previously for a genus of mammals, and the correct name for the genus is ''Avicularia'', making this species ''Avicularia affinis''. It was subsequently transferred to ''Brachypelma'' in 1936 and then to ''Euathlus ''Euathlus'' is a genus of South American tarantulas that was first described by Anton Ausserer in 1875. These spiders are medium sized and are usually found in high elevations in the Andes. It is a senior synonym of ''Paraphysa'', and was former ...'' in 2017.

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] |
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 ...

Tarantula
Tarantulas comprise a group of large and often hairy spiders of the family Theraphosidae. , 1,040 species have been identified, with 156 genera. The term "tarantula" is usually used to describe members of the family Theraphosidae, although many other members of the same infraorder (Mygalomorphae) are commonly referred to as "tarantulas" or "false tarantulas". Some of the more common species have become popular in the exotic pet trade. Many New World species kept as pets have setae known as urticating hairs that can cause irritation to the skin, and in extreme cases, cause damage to the eyes. Overview Like all arthropods, the tarantula is an invertebrate that relies on an exoskeleton for muscular support.Pomeroy, R. (2014, February 4). Pub.

Chile
Chile, officially the Republic of Chile, is a country in the western part of South America. It is the southernmost country in the world, and the closest to Antarctica, occupying a long and narrow strip of land between the Andes to the east and the Pacific Ocean to the west. Chile covers an area of , with a population of 17.5 million as of 2017. It shares land borders with Peru to the north, Bolivia to the north-east, Argentina to the east, and the Drake Passage in the far south. Chile also controls the Pacific islands of Juan Fernández, Isla Salas y Gómez, Desventuradas, and Easter Island in Oceania. It also claims about of Antarctica under the Chilean Antarctic Territory. The country's capital and largest city is Santiago, and its national language is Spanish. Spain conquered and colonized the region in the mid-16th century, replacing Inca rule, but failing to conquer the independent Mapuche who inhabited what is now south-central Chile. In 1818, after declaring in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Brachypelma
''Brachypelma'' is a genus of spiders in the family Theraphosidae (tarantulas). They may have bodies up to long with legs of similar or greater lengths. Some species have brightly colored legs, with red or orange marks and rings. The taxonomy of the genus and its species has been the subject of considerable debate. In 2020, the genus was split, with a group of species (the "red rump" tarantulas) being moved to a new genus, '' Tliltocatl''. As now circumscribed, the genus ''Brachypelma'' is found only in Mexico. Many species of both genera are popular with tarantula keepers as pets; the females in particular are long lived. All species are protected, and trade is regulated under CITES. Although they are bred in captivity, they continue to be exported in large numbers. Members of the reduced genus ''Brachypelma'' (the "red leg" group) are considered to be in most urgent need of further conservation efforts.

Euathlus
''Euathlus'' is a genus of South American tarantulas that was first described by Anton Ausserer in 1875. These spiders are medium sized and are usually found in high elevations in the Andes. It is a senior synonym of ''Paraphysa'', and was formerly considered a senior synonym of '' Brachypelma'', but this was later rejected. Diagnosis Males own a palpal bulb with two prolateral keels, with the tip curved retrolaterally. The tibial apophyses has retrolateral spines and a spine on the retrolateral branch which almost reached the apex. And a urticating patch in the center of the opisthosoma, which own mainly type 3 and 4 urticating hairs. Females also can be distinguished by two 4 sided spermathecal receptacles, with sphere like chambers. Species it contains fourteen species, found in Argentina, Chile and Peru: *'' Euathlus affinis'' (Nicolet, 1849) – Chile *'' Euathlus antai'' Perafán & Pérez-Miles, 2014 – Chile *'' Euathlus atacama'' Perafán & Pérez-Miles, 2014 â ...
