Genera Chactidae contains the following genera: *''Anuroctonus'' Pocock, 1893 *''Auyantepuia'' (Gonzalez-Sponga, 1978) *''Broteochactas'' Pocock, 1893 *''Brotheas'' C.L.

Scorpion Families
Scorpions are predatory arachnids of the Order (biology), order Scorpiones. They have eight legs and are easily recognized by a pair of Chela (organ), grasping pincers and a narrow, segmented tail, often carried in a characteristic forward curve over the back and always ending with a stinger. The evolutionary history of scorpions goes back Silurian, 435 million years. They mainly live in deserts but have adapted to a wide range of environmental conditions, and can be found on all continents except Antarctica. There are over 2,500 described species, with 22 extant (living) families recognized to date. Their Taxonomy (biology), taxonomy is being revised to account for 21st-century genomic studies. Scorpions primarily prey on insects and other invertebrates, but some species hunt vertebrates. They use their pincers to restrain and kill prey, or to prevent their own predation. The Scorpion sting, venomous sting is used for offense and defense. During courtship, the male and female ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Anuroctonus Pococki
''Anuroctonus pococki'', also known as the California swollen-stinger scorpion, is a species of scorpion of the family Chactidae. It is native to the coast ranges of Southern California, and into Baja California in North America. This is the only scorpion from the genus '' Anuroctonus'' in Baja California. This scorpion, at , is large compared to other scorpions found in the region. These scorpions have very large, black-tipped claws, and a "swollen region just before the stinger" on their telsons, most prominent in mature males. California swollen-stinger scorpions are nocturnal ambush predators who mostly wait in their burrows for bypassing prey species. Females dig burrows up to deep, while burrows created by males are usually underground. This scorpion was first formally named in 2004. Stings from the mildly venomous California swollenstinger scorpion are rare. They are usually painful but non-serious and resolve after 24 hours; however, in some cases stings may pose seri ...

Eugène Simon
Eugène Louis Simon (; 30 April 1848 – 17 November 1924) was a French naturalist who worked particularly on insects and spiders, but also on birds and plants. He is by far the most prolific spider Taxonomy (biology), taxonomist in history, describing over 4,000 species. Work on spiders His most significant work was ''Histoire Naturelle des Araignées'' (1892–1903), an encyclopedic treatment of the spider genera of the world. It was published in two volumes of more than 1000 pages each, and the same number of drawings by Simon. Working at the National Museum of Natural History (France), Muséum National d'Histoire Naturelle in Paris, it took Simon 11 years to complete, while working at the same time on devising a taxonomic scheme that embraced the known taxa. Simon described a total of 4,650 species, and as of 2013 about 3,790 species are still considered valid. The International Society of Arachnology offers a Simon Award recognising lifetime achievement. The Eocene fos ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
