What scorpion had the deadliest sting?

[Smokehound714]

Hemiscorpius are the most dangerous IMO because of their cytotoxic venom. It's similar to the venom of Crotalus

Very interesting. That's not a type of venom I would associate with a scorpion. Quite unique.

Cytotoxic venoms may cause some morbidity and the occasional death, but generally aren't lethal. Neurotoxins are generally far more likely to cause death as they directly effect the diaphram and even the heart. Blood destroying venoms such as hemorrhagins, pro and anticoagulants can also be devestating. These are found in many of the super hot Australian snakes as well as a few crotalids, carpet vipers, and most of the lethal rear-fanged colubrids. This is why cytotoxic snake species, like a lot of the Asian tree vipers (Trimeresurus sp. for example), while they can be extremely dangerous, don't usually hold a candle to the highly neurotoxic and hemorrhagic species like kraits, cobras, Russell's vipers, mambas, some rattlesnakes, and the carpet vipers. Also, N. American and S. American crotalus aren't especially known for cytotoxicity, but rather hemorrhagins, myotoxins, and actually, as studies are beginning to show, many are highly neurotoxic. I feel like people tend to brush off neurotoxic venom because it's a less painful route, but imagine taking a bite from a krait or some other Neurotoxic species and while you're waiting on your front lawn for the ambulance you start feeling that weight on your chest like you can't take a breath and your eyelids begin to droop. Pretty damn terrifying. Not to mention that presynaptic neurotoxins, like found in kraits and some rattlesnakes, will completely fry your neural pathways and can't be reversed with antivenom. Your body has to literally reestablish new pathways and in some cases people have to learn to speak and walk all over again.
