18. Deathstalker
The problem with this scorpion is that there are several species that use the same common name. Only the Leiurus quinquestriatus variety is the true Deathstalker. Their sting is the most venomous of any scorpion, painful, but not lethal, not to a healthy adult human. They hang out in North Africa parts of the Middle East, and your creepy neighbor’s black-light terrarium.
