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 venom of L. quinquestriatus is among the most potent scorpion toxins. It severely affects the cardiac and pulmonary systems. Human fatalities, often children, have been confirmed by clinical reports. [25] The median lethal dose of venom (LD 50) for this species was measured at 0.16 - 0.50 mg/kg mice. [26]
There are about 50 species of scorpions that cause fatal scorpionism worldwide. [10] The venom from Leiurus abdullahbayrami can be very toxic.

Parabuthus transvaalicus is a dangerous, medically significant scorpion, which can both sting and spray its kurtoxin venom. [2] The first droplet of venom differs from the rest, and is referred to as "pre-venom". [4] A further potassium channel inhibitor, parabutoxin, has been isolated from the venom of P. transvaalicus.
