Parabuthus Brevimanus
''Parabuthus brevimanus'' is a species of scorpion from southern Africa, that ranges from southern Angola to Namibia and western South Africa, where its range extends south of the Orange River. Habits It is a semipsammophilous species that inhabits compacted or semicompacted sandy or gravelly substrates, wherein it burrows either in open ground, or at the base of shrubs or grass tufts. The rows of long, comb-like bristlesAlso referred to as macrosetae or "sand combs" on the lower tarsi (third distal segment) of the four front legs are suggestive of its habits and habitat choice. It prefers substantially more solid substrates than the sand dunes occupied by its close relatives '' P. kuanyamarum'' and '' P. nanus''. It is syntopic with '' P. granulatus'' throughout its range, but less often so with '' P. laevifrons'', '' P. schlechteri'', and '' P. villosus'' than its near relative '' P. gracilis''. Relationships and characters The species is basal to the clade that incorporates t ... [...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 ...

Parabuthus Villosus
''Parabuthus villosus'', the black hairy thick-tailed scorpion, is a species of scorpion from southern Africa, where it ranges from the Northern Cape to Namibia. It is the largest species of the Buthidae, measuring up to 18 cm, and its diet may include lizards and mice. The species is often active at dawn and dusk, but takes refuge by day in a variety of shelters. It resembles ''Parabuthus transvaalicus ''Parabuthus transvaalicus'' (known as the Transvaalicus thick-tailed scorpion, South African thick tail, or giant deathstalker) is a species of venomous scorpion from semi-arid parts of southern Africa.

Process (anatomy)
In anatomy, a process ( la, processus) is a projection or outgrowth of tissue from a larger body. For instance, in a vertebra, a process may serve for muscle attachment and leverage (as in the case of the transverse and spinous processes), or to fit (forming a synovial joint), with another vertebra (as in the case of the articular processes).Moore, Keith L. et al. (2010) ''Clinically Oriented Anatomy'', 6th Ed, p.442 fig. 4.2 The word is used even at the microanatomic level, where cells can have processes such as cilia or pedicels. Depending on the tissue, processes may also be called by other terms, such as ''apophysis'', ''tubercle'', or ''protuberance''. Examples Examples of processes include: *The many processes of the human skull: ** The mastoid and styloid processes of the temporal bone ** The zygomatic process of the temporal bone ** The zygomatic process of the frontal bone ** The orbital, temporal, lateral, frontal, and maxillary processes of the zygomatic bone ...

Tubercle (anatomy)
In anatomy, a tubercle (literally 'small tuber', Latin for 'lump') is any round nodule, small eminence, or warty outgrowth found on external or internal organs of a plant or an animal. In plants A tubercle is generally a wart-like projection, but it has slightly different meaning depending on which family of plants or animals it is used to refer to. In the case of certain orchids and cacti, it denotes a round nodule, small eminence, or warty outgrowth found on the lip. They are also known as podaria (singular ''podarium''). When referring to some members of the pea family, it is used to refer to the wart-like excrescences that are found on the roots. In fungi In mycology, a tubercle is used to refer to a mass of hyphae from which a mushroom is made. In animals When it is used in relation to certain dorid nudibranchs such as '' Peltodoris nobilis'', it means the nodules on the dorsum of the animal. The tubercles in nudibranchs can present themselves in different ways: ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Trichobothria
Trichobothria (singular trichobothrium) are elongate setae ("hairs") present in arachnids, various orders of insects, and myriapods that function in the detection of airborne vibrations and currents, and electrical charge. In 1883, Friedrich Dahl observed that they were deflected by the sound waves from a violin and labelled them 'hearing hairs'. Morphology Unlike the ordinary setae, which are tapered, the trichobothria have the same gauge throughout their length. They fit into the bottom of a broad and deep cup to which connects a membrane with extreme flexibility which adds an extraordinary mobility to them. The least air vibration is able to get them moving and to excite the small group of sensory cells which ensures their innervation. Distribution Trichobothria are present in most orders of the Arachnida, except in Solifugae, Ricinulei and Opiliones (Grassé, 1949). Although the distribution of trichobothria on the bodies of arachnids is often used by systematists (especial ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chela (organ)
A chela ()also called a claw, nipper, or pinceris a pincer (biology), pincer-like organ at the end of certain limbs of some arthropods. The name comes from Ancient Greek , through New Latin '. The plural form is chelae. Legs bearing a chela are called chelipeds. Another name is ''claw'' because most chelae are curved and have a sharp point like a claw. Chelae can be present at the tips of arthropod legs as well as their pedipalps. Chelae are distinct from spider chelicerae in that they do not contain venomous glands and cannot distribute venom.

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. At present, the only ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carapace
A carapace is a Dorsum (biology), dorsal (upper) section of the exoskeleton or shell in a number of animal groups, including arthropods, such as crustaceans and arachnids, as well as vertebrates, such as turtles and tortoises. In turtles and tortoises, the underside is called the plastron. Crustaceans In crustaceans, the carapace functions as a protective cover over the cephalothorax (i.e., the fused head and thorax, as distinct from the abdomen behind). Where it projects forward beyond the eyes, this projection is called a rostrum (anatomy), rostrum. The carapace is Calcification, calcified to varying degrees in different crustaceans. Zooplankton within the phylum Crustacea also have a carapace. These include Cladocera, ostracods, and Isopoda, isopods, but isopods only have a developed "cephalic shield" carapace covering the head. Arachnids In arachnids, the carapace is formed by the fusion of prosomal tergites into a single Plate (animal anatomy), plate which carries the e ...

Parabuthus
''Parabuthus'', commonly known as the thick-tailed scorpion, is a genus of large and highly venomous Afrotropical scorpions, that show a preference for areas of low rainfall. Their stings are medically important and human fatalities have been recorded.Larsen, Norman. Biodiversity Explorer, IZIKO. Scorpion stings and venom/ref> Characteristics They have thick and strong tails, with typically a rough surface to the first (proximal) and sometimes second segment, that is used to produce a warning sound when rubbed against the sting (save '' Parabuthus distridor, P. distridor''). Their thick tails are also employed in excavating their shallow burrows, as several are adapted to sandy environments. Some flatter-bodied species, however, take refuge in rock crevasses. Due to their stings' quick-acting venom, they rely to lesser extent on their slender pinchers (chelae) to hold onto prey. Three species, '' P. schlechteri'', '' P. transvaalicus'', and '' P. villosus'' are thought to be abl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
