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.

Tliltocatl
''Tliltocatl'' is a genus of North American tarantulas that was split off from ''Brachypelma'' in 2020. They are also large burrowing tarantulas, but don't have the striking red leg markings of ''Brachypelma'' species. A female '' T. vagans'' can grow up to long and legs can get as long as . They are found predominantly in Mexico, with some species native to Central America. The name is derived from two Nahuatl words, "tlil", meaning "black", and "tocatl", meaning "spider". Habitat destruction and collection for the pet trade has led to this and ''Brachypelma'' to be protected under International Convention on International Trade of Endangered Species rules, beginning with ''B. smithi''. Description The carapace is about as long as wide, though the sternum is longer than wide. The first legs are the longest, but all four legs have undivided scopuli on its tarsus. Stridulating hairs are present on both the retrolateral and prolateral faces of the second segment of the pedipalp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Brachypelma Smithi
''Brachypelma smithi'' is a species of spider in the family Theraphosidae (tarantulas) native to Mexico. It has been confused with ''Brachypelma hamorii''; both have been called Mexican redknee tarantulas. Mexican redknee tarantulas are a popular choice as pets among tarantula keepers. Many earlier sources referring to ''B. smithi'' either relate to ''B. hamorii'' or do not distinguish between the two species. ''B. smithi'' is a terrestrial tarantula native to Pacific coast of the Mexican state of Guerrero. Description ''Brachypelma smithi'' is a large spider. A sample of seven females had a total body length (excluding chelicerae and spinnerets) in the range . A sample of eight males were slightly smaller, with a total body length in the range . Although males have slightly shorter bodies, they have longer legs. The fourth leg is the longest, measuring in the type male and in a female. The legs and palps are bluish black with three distinctly colored rings: dark ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Brachypelma Klaasi
''Brachypelma klaasi'' (also known as the Mexican pink tarantula) is a tarantula endemic to Mexico and it is the rarest of the genus ''Brachypelma''. Appearance The setae of this species have a uniformly rusty appearance. The coloration is very similar to that of the six species of ''Brachypelma'' that are endemic to the west coast. '' B. boehmei'' is similar, having black tarsi, orange-yellow metatarsi, tibias and patellas, black femora and coxae and orange-yellow hairs on the opistosoma. It differs only in the carapace, which is yellow-orange in ''B. boehmei'' and black in ''B. klaasi''. Another very similar species is '' B. baumgarteni''. Adults of ''B. klaasi'' have a body length of about 6–7.5 cm with a 16 cm legspan. Distribution ''B. klaasi'' is found at elevations of 300–1400 m above sea level on the western slopes of the Sierra Madre Occidental and some areas on the western limits of the Trans-Mexican Volcanic Belt in Jalisco and Nayarit states.

Brachypelma Albiceps
''Brachypelma albiceps'' is a species of spider in the tarantula family, Theraphosidae. It is known as the Mexican golden red rump tarantula or the Amula red rump tarantula. The carapace is a light golden color and the abdomen dark, covered with long red hairs. Females typically live for about 15 years (up to 20). Males usually live about 5 years or up to 12 months after the last molt. Description Females of ''Brachypelma albiceps'' have a body length of about 65 mm. The fourth leg is longest at about 60 mm. The carapace is covered with fine hair; its apparent color depends on the illumination, varying from sandy grey through to rose or yellow. The pedipalps and the first two pairs of legs may be lighter than the last two pairs of legs. The abdomen is dark with bright red longish hairs (setae). The spermatheca has two rounded seminal receptacles. Taxonomy ''Brachypelma albiceps'' has a somewhat tangled taxonomic history. In 1897, F. O. Pickard-Cambridge described the s ...

Brachypelma Boehmei
''Brachypelma boehmei'' (also known as the Mexican fireleg, or the Mexican rustleg tarantula) is a tarantula native to Mexico in Guerrero state. These long-lived tarantulas prefer burrowing and hiding in dry scrubland. As with all closely related tarantula species, they defend themselves with urticating hair when provoked. Appearance and characteristics The Mexican fireleg resembles its better-known relative, the Mexican redknee tarantula (''Brachypelma hamorii'', formerly confused with ''Brachypelma smithi''), in its dramatic orange and black coloration, though the adults of the species range from 5 to 6 inches in size. This species of tarantula has a slower growth rate than many of the larger South American tarantula species. The black femora (upper legs) provide a dark dividing band between the rich orange color of the carapace and lower legs. Unlike the orange joints of ''Brachypelma hamorii'', the legs of this species are a bright, fiery red on the patellae (or knees), ...

Avicularia
''Avicularia'' is a genus of the family Theraphosidae containing various species of arboreal tarantulas. The genus is native to Panama, the Caribbean and tropical South America. Each species in the genus has very distinguishable pink foot pads. Species belonging to this genus are amongst the relatively small exception of tarantulas that can jump moderate distances as juveniles, with most tarantulas being limited to lunges of 3-4 centimeters. Urticating hairs are distinct to new world tarantulas including the Avicularia that are attached to the spider's cuticle ''via'' a stalk. These spiny, barbed hairs are used as a defense against potential intruders as well as embedded into silk to protect the egg sac. In active defense, the hairs are released by contact with the stimulus and rubbed in. At least three species of Avicularia are threatened by habitat loss and illegal trafficking, due to their popularity as exotic pets. '' Avicularia avicularia'' are among the tarantulas most ...

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.

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 ...

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 ...

Arachnology
Arachnology is the scientific study of arachnids, which comprise spiders and related invertebrates such as scorpions, pseudoscorpions, and harvestmen. Those who study spiders and other arachnids are arachnologists. More narrowly, the study of spiders alone ( order Araneae) is known as araneology. The word "arachnology" derives from Greek , ''arachnē'', "spider"; and , ''-logia'', "the study of a particular subject". Arachnology as a science Arachnologists are primarily responsible for classifying arachnids and studying aspects of their biology. In the popular imagination, they are sometimes referred to as spider experts. Disciplines within arachnology include naming species and determining their evolutionary relationships to one another (taxonomy and systematics), studying how they interact with other members of their species and/or their environment (behavioural ecology), or how they are distributed in different regions and habitats (faunistics). Other arachnologists perform ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pedipalp
Pedipalps (commonly shortened to palps or palpi) are the second pair of appendages of chelicerates – a group of arthropods including spiders, scorpions, horseshoe crabs, and sea spiders. The pedipalps are lateral to the chelicerae ("jaws") and anterior to the first pair of walking legs. Overview Pedipalps are composed of six segments or articles: the coxa, the trochanter, the femur, the short patella, the tibia, and the tarsus. In spiders, the coxae frequently have extensions called maxillae or gnathobases, which function as mouth parts with or without some contribution from the coxae of the anterior legs. The limbs themselves may be simple tactile organs outwardly resembling the legs, as in spiders, or chelate weapons ( pincers) of great size, as in scorpions. The pedipalps of Solifugae are covered in setae, but have not been studied in detail. Comparative studies of pedipalpal morphology may suggest that leg-like pedipalps are primitive in arachnids.
