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.
In Central America, most scorpion stings are mildly toxic to humans. However, Panama has reported an incidence of 52 cases per 100,000 people in 2007. Between 1998 and 2006, 28 people have died as result of scorpion stings. In Panama, the taxa of scorpions responsible for these deaths belong to the genus Tityus.

Scorpions are predatory arachnids of the order Scorpiones.

In Guyana, in a 12-month period three people died, two children and a 30-year-old man. In all these cases, they experienced local pain that soon developed into vomiting and persistent leukocytosis. They all died after developing cardiopulmonary failure and dysrhythmias. [6] The median lethal dose from this species is 3.13 mg / kg (i.p.). [7]
