They are small arachnids with a flat, pear-shaped body, and pincer-like pedipalps that resemble those of scorpions. They usually range from 2 to 8 mm (0.08 to 0.31 in) in length. [3] The largest known species is Garypus titanius of Ascension Island [4] at up to 12 mm (0.5 in). [5] [6] Range is generally smaller at an average of 3 mm (0.1 in). [2]
The deathstalker is one of the most dangerous species of scorpions. [10] [11] Its venom is a powerful mixture of neurotoxins, with a low lethal dose. [12]While a sting from this scorpion is extraordinarily painful, it normally would not kill a healthy adult human.
The Arizona bark scorpion (Centruroides sculpturatus, once included in Centruroides exilicauda) is a small light brown scorpion common to the Sonoran Desert in the southwestern United States and northwestern Mexico. An adult male can reach 8 centimetres (3.1 in) of body length, while a female is slightly smaller, with a maximum length of 7 ...
Scorpions detect their prey with mechanoreceptive and chemoreceptive hairs on their bodies and capture them with their claws. Small animals are merely killed with the claws, particularly by large-clawed species. Larger and more aggressive prey is given a sting. [86] [87] Scorpions, like other arachnids, digest their food externally.
Scorpions often conjure images of a dangerous, sneaky and treacherous animal, but this impression is largely incorrect or biased. Geotze: Scorpions get a bad rap. They are secretive, unassuming ...
Within its range this species prefers mesic mixed woodland, being readily found under logs, stones, or the bark of standing dead trees. It readily enters homes and other human structures and can fit through very fine crevices or gaps. As with all scorpions it may easily be found using blacklights due to the fluorescence of the exoskeleton.
A scorpion sting is an injury caused by the stinger of a scorpion resulting in the medical condition known as scorpionism, which may vary in severity. The anatomical part of the scorpion that delivers the sting is called a "telson". In typical cases, scorpion stings usually result in pain, paresthesia, and variable swelling.
Victims of the sting have reported local effects (intense pain, redness and swelling). Systemic effects include heart malfunctions, remote internal bleeding, visual disturbance, and respiratory problems. The venom is very powerful and considered among the most potent among scorpions, and is known to cause human death. [7]
