Mandarin Chinese
Mandarin ( ; zh, s=, t=, p=Guānhuà, l=Mandarin (bureaucrat), officials' speech) is the largest branch of the Sinitic languages. Mandarin varieties are spoken by 70 percent of all Chinese speakers over a large geographical area that stretches from Yunnan in the southwest to Xinjiang in the northwest and Heilongjiang in the northeast. Its spread is generally attributed to the greater ease of travel and communication in the North China Plain compared to the more mountainous south, combined with the relatively recent spread of Mandarin to frontier areas. Many varieties of Mandarin, such as Southwestern Mandarin, those of the Southwest (including Sichuanese dialects, Sichuanese) and the Lower Yangtze Mandarin, Lower Yangtze, are not mutually intelligible with the Beijing dialect (or are only partially intelligible). Nevertheless, Mandarin as a group is often placed first in lists of languages by number of native speakers (with nearly one billion). Because Mandarin originated in ...

Yellow Sac Spider
''Cheiracanthium'', commonly called yellow sac spiders, is a genus of Araneomorphae, araneomorph spiders in the family Cheiracanthiidae, and was first described by Carl Ludwig Koch in 1839. They are usually pale in colour, and have an spider anatomy#Abdomen, abdomen that can range from yellow to beige. Both sexes range in size from . They are unique among common house spiders because their tarsus (arthropod), tarsi do not point either outward, like members of ''Tegenaria'', or inward, like members of ''Araneus'', making them easier to identify. Venom Though they are beneficial predators in agricultural fields, they are also known to be mildly venomous to humans. Painful bites may be incurred from species such as ''Cheiracanthium punctorium, C. punctorium'' in Europe, ''Cheiracanthium mildei, C. mildei'' in Europe and North America, ''Cheiracanthium inclusum, C. inclusum'' in the Americas, ''C. lawrencei'' in South Africa and ''C. japonicum'' in Japan.

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 1850s 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) (Club ...

Chelicerae
The chelicerae () are the arthropod mouthparts, mouthparts of the subphylum Chelicerata, an arthropod group that includes arachnids, horseshoe crabs, and sea spiders. Commonly referred to as "jaws", chelicerae may be shaped as either articulated fangs, or as a type of pincer_(biology), pincers. Some chelicerae, such as those found on nearly all spiders, are hollow and contain (or are connected to) venom glands, used to inject venom into prey or a perceived threat. Both pseudoscorpions and Opiliones , harvestmen have additional structures on their chelicerae that are used for grooming (papillae in pseudoscorpions, cheliceral teeth in Opiliones). In ''Paratrechalea'', males and females have shown to have a chelicerae dimorphism, because the chelicerae is used as a mating signal for females. Types Chelicerae can be divided into three kinds: jackknife chelicerae, scissor chelicerae, and three-segmented wikt:chelate, chelate chelicerae. Jackknife chelicerae The jackknife chelicer ...
