Theraphosa
''Theraphosa'' is a genus of South American tarantulas that was first described by Tamerlan Thorell in 1870. The Theraphosa spiders are some of the largest known to science, and are usually called Pinkfoot Goliaths in english. it contains three species, found in Guyana, Brazil, Venezuela, and Colombia. They stridulate by rubbing setae on their pedipalps and legs. Diagnostic Tarantulas of this genus are characterized by their large size, and the lack of long hairs in the patella and tibia sections of the legs. It can also be further distinguished by the presence of stridulating hairs on the prolateral coxae 1 and 2. Females also own a unique single spermatheca. Behavior This tarantulas are found in holes in the ground, usually abandoned burrows, which they adopt and use as their own. They are usually found near rivers, and eat a great amount of invertebrates and very small vertebrates, such as small frogs and lizards. Species the World Spider Catalog has accepted the foll ...

Theraphosa Blondi
The Goliath birdeater (''Theraphosa blondi'') belongs to the tarantula family Theraphosidae. Found in northern South America, it is the largest spider in the world by mass () and body length (up to ), and second to the giant huntsman spider by leg span. It is also called the Goliath tarantula or Goliath bird-eating spider; the practice of calling theraphosids "bird-eating" derives from an early 18th-century copper engraving by Maria Sibylla Merian that shows one eating a hummingbird. Despite the spider's name, it rarely preys on birds. Physical description These spiders can have a leg span up to , a body length of up to and can weigh up to .Goliath Bird-Eating Spider , Arkive Birdeaters are one of the few tarantula species that lack tibial spurs, located on the first pair of legs of mos ...

Theraphosa Apophysis
''Theraphosa apophysis'' is a species of spider in the family Theraphosidae, found in Venezuela and Brazil. Description ''Theraphosa apophysis'' generally resembles ''Theraphosa blondi'', and reaches a similar size. Young ''T. apophysis'' spiders have pink shading at the end of each leg, which fades with each moult. ''T. apophysis'' has an additional stridulating organ on the coxa of the second leg and thinner femora than ''T. blondi''. The male ''T. apophysis'' has tibial apophyses (projections) – hence the species name. The ground colour of both sexes is coffee brown; the legs and opisthosoma have long scattered orange-brown hairs, with long orange hair on the femora. Mature males have a metallic sheen, described as "wine red" in colour, on the cephalothorax, the dorsal surface of the chelicerae, the pedipalps, and the coxa, trochanter and femur of the legs, as well as the patella of the first leg. The female specimen on which the species was described ha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Theraphosa Stirmi
''Theraphosa stirmi'' is a species of tarantula belonging to the family Theraphosidae. It is known as the burgundy goliath bird eater. Distribution This species occurs in Guyana and Brazil, in tropical South America. Description In ''Theraphosa stirmi'' the carapace can reach a length of and a width of . The longest leg (the fourth) in a male had a total length of . Coloration of these heavy-bodied spiders varies from rusty brown or rich burgundy-brown to dark brown, with reddish setae on legs and abdomen and white lines on the legs. Adult males lack mating spurs or tibial apophyses. Spiderlings and juveniles have pink tarsi on the front two pairs of legs. Behavior These tarantulas hide themselves in long tubes that they dig under the surface or use abandoned rodent burrows. It is a crepuscular and nocturnal species and it is quite defensive. When threatened this species will stridulate (hiss) to warn predators, it may also rear up and expose its fangs. Another self-defence ...

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.

Spiders Of South America
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 separate t ...

Stridulation
Stridulation is the act of producing sound by rubbing together certain body parts. This behavior is mostly associated with insects, but other animals are known to do this as well, such as a number of species of fish, snakes and spiders. The mechanism is typically that of one structure with a well-defined lip, ridge, or nodules (the "scraper" or ''plectrum'') being moved across a finely-ridged surface (the "file" or ''stridulitrum''—sometimes called the ''pars stridens'') or vice versa, and vibrating as it does so, like the dragging of a phonograph needle across a vinyl record. Sometimes it is the structure bearing the file which resonates to produce the sound, but in other cases it is the structure bearing the scraper, with both variants possible in related groups. Common onomatopoeic words for the sounds produced by stridulation include ''chirp'' and ''chirrup''. Arthropod stridulation Insects and other arthropods stridulate by rubbing together two parts of the body. These a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tamerlan Thorell
Tord Tamerlan Teodor Thorell (3 May 1830 – 22 December 1901) was a Sweden, Swedish arachnologist. Thorell studied spiders with Giacomo Doria at the Museo Civico di Storia Naturale de Genoa. He corresponded with other arachnologists, such as Octavius Pickard-Cambridge, Eugène Simon and Thomas Workman (entomologist), Thomas Workman. He described more than 1,000 spider species during his time from the 1850 to 1900. Thorell wrote: ''On European Spiders'' (1869) and ''Synonym of European Spiders'' (1870-73). Taxonomic honors The Orb-weaver spider genus ''Thorellina'' and the jumping spider genus ''Thorelliola'' are named after him, as well as about 30 species of spiders: * ''Araneus thorelli'' (Roewer, 1942) (Myanmar) (Araneidae) * ''Gasteracantha thorelli'' Keyserling, 1864 (Madagascar) (Araneidae) * ''Leviellus thorelli'' (Ausserer, 1871) (Europe) (Araneidae) * ''Mandjelia thorelli'' (Raven, 1990) (Queensland) (Barychelidae) * ''Clubiona thorelli'' Roewer, 1951 (Sumatra) (Clubi ...
