8. Deathstalker Scorpion
Leiurus quinquestriatus is a species of scorpion native to North Africa all the way to the Middle East. Displaying bright green and golden yellow coloration, they grow to about 80mm long; some even keep them as exotic pets.
However, they are considered the deadliest of all scorpions. Their venom is a combination of neurotoxins, with toxicity levels of 0.16–0.50 mg/kg, indicating that this species has one of the most toxic venoms ever. A sting from a deathstalker scorpion always leads to anaphylaxis and death by accumulation of fluid in the lungs. Even when antivenom is available, there is always the chance that the venom is resistant to treatment.
