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.
The sting impairs the left ventricle contractility and heart failure occurs. It is very important that early echocardiographic examination is done in patients who have been stung. [13] [14] The venom was tested in rats, and its effects were compared to the effects of Arabian fat-tailed scorpion (Androctonus crassicauda) venom.
The Buthidae are the largest family of scorpions, containing about 100 genera and 1339 species as of 2022. [2] A few very large genera (Ananteris, Centruroides, Compsobuthus, or Tityus) are known, but a high number of species-poor or monotypic ones also exist. [2] New taxa are being described at a rate of several new species per year. [2]
Tityus scorpions are best known for their venom and potent sting. [4] [5] 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. [6]
The scorpions’ stings seem to be benign to humans. “So far, we only know these two new species have a narrow range in the Pilbara, restricted to creeks and drainage lines, so we need to ...
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. [ 1 ] [ 3 ] Their stings are medically important and human fatalities have been recorded.
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.
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.
