Buthida
Buthoidea is the largest Taxonomic rank, superfamily of scorpions. Its members are known as fat-tailed scorpions and bark scorpions. A few very large genera (''Ananteris'', ''Centruroides'', ''Compsobuthus'', or ''Tityus (genus), Tityus'') are known, but a high number of species-poor or monotypic ones also exist.Rein, Jan Ove (2008): The Scorpion Files Buthidae Retrieved June 25, 2008. They occur in the warmer parts of every major landmass on Earth, except on New Zealand. The superfamily was established by Carl Ludwig Koch in 1837. Taxonomy Five families are placed into Buthoidea, two extant families Buthidae and Microcharmidae, plus three extinct families. *†Archaeobuthidae (Lebanese amber, Hauterivian) *Buthidae (Modern, Cenomanian - Recent) *Microcharmidae (Modern, Recent) *†Palaeoburmesebuthidae (Burmese amber, Cenomanian) *†Protobuthidae ( Grès à Voltzia Formation, Anisian) *†Sucinlourencoidae (Burmese amber, Cenomanian) References {{Taxonbar, from1=Q3716798 ...

Buthidae
The Buthidae are the largest family of scorpions, containing about 100 genera and 1339 species as of 2022. A few very large genera ('' Ananteris'', '' Centruroides'', '' Compsobuthus'', or '' Tityus'') are known, but a high number of species-poor or monotypic ones also exist. New taxa are being described at a rate of several new species per year. They have a cosmopolitan distribution throughout tropical and subtropical environments worldwide. Together with four other families, the Buthidae make up the superfamily Buthoidea. The family was established by Carl Ludwig Koch in 1837. Around 20 species of medically important (meaning potentially lethal to humans) scorpions are known, and all but one of these ('' Hemiscorpius lepturus'') are members of the Buthidae. In dead specimens, the spine beneath the stinger, characteristic for this family, can be observed.

Scorpion Taxonomy
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] |
Tityus (genus)
''Tityus'' is a large genus of thick-tailed scorpions (family Buthidae), the namesake of its subfamily Tityinae. As of 2021, ''Tityus'' contains more than 220 described species distributed in Central America and South America, from Costa Rica to Argentina. Species in the genus ''Tityus'' have been studied for hundreds of years, long before the taxonomic classification was put in place. ''Tityus'' tend to be of medium size for scorpions, roughly 50 to 70 millimeters long. They are dark brown or red in color, and can exhibit sexual dimorphism. They can live in a variety of environments, ranging from urban to arid mountains to the Amazon Rainforest. ''Tityus'' scorpions are best known for their venom and potent sting. The genus contains several dangerously venomous scorpions, the best known of which is the Brazilian yellow scorpion, '' T. serrulatus''. Its venom can cause severe illness (including pancreatitis), and in the young, old and infirm even death. Some experts have argued ...

Centruroides
''Centruroides'' is a genus of scorpions of the family Buthidae. Several North American species are known by the common vernacular name bark scorpion. Numerous species are extensively found throughout the southern United States, Mexico, Central America, the Antilles and northern South America. Some are known for their interesting patterning or large size (among Buthidae); most if not all fluoresce strongly under ultraviolet illumination, except after moulting. They contain several highly venomous species, and fatalities are known to occur. The venom of the Mexican scorpion ''Centruroides limpidus limpidus'' contains the neurotoxin Neurotoxins are toxins that are destructive to nervous tissue, nerve tissue (causing neurotoxicity). Neurotoxins are an extensive class of exogenous chemical neurological insult (medical), insultsSpencer 2000 that can adversely affect function ...s Cll1 and Cll2.

Hauterivian
The Hauterivian is, in the geologic timescale, an age in the Early Cretaceous Epoch or a stage in the Lower Cretaceous Series. It spans the time between 132.6 ± 2 Ma and 125.77 (million years ago). The Hauterivian is preceded by the Valanginian and succeeded by the Barremian. Stratigraphic definitions The Hauterivian was introduced in scientific literature by Swiss geologist Eugène Renevier in 1873. It is named after the Swiss town of Hauterive at the shore of Lake Neuchâtel. The base of the Hauterivian is defined as the place in the stratigraphic column where the ammonite genus '' Acanthodiscus'' first appears. A reference profile for the base (a GSSP) was officially ratified by the International Union of Geological Sciences in December of 2019, and is placed in La Charce, France. The top of the Hauterivian (the base of the Barremian) is at the first appearance of ammonite species '' Spitidiscus hugii''. In the ammonite biostratigraphy of the Tethys domain, the ...

Arachnid Superfamilies
Arachnids are arthropods in the class Arachnida () of the subphylum Chelicerata. Arachnida includes, among others, spiders, scorpions, ticks, mites, pseudoscorpions, harvestmen, camel spiders, whip spiders and vinegaroons. Adult arachnids have eight legs attached to the cephalothorax. In some species the frontmost pair of legs has converted to a sensory function, while in others, different appendages can grow large enough to take on the appearance of extra pairs of legs. Almost all extant arachnids are terrestrial, living mainly on land. However, some inhabit freshwater environments and, with the exception of the pelagic zone, marine environments as well. They comprise over 110,000 named species, of which 51,000 are species of spiders. The term is derived from the Greek word (''aráchnē'', 'spider'), from the myth of the hubristic human weaver Arachne, who was turned into a spider. Morphology Almost all adult arachnids have eight legs, unlike adult insects which all h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
