They’re two of the most venomous pests on planet Earth.
While black widows are known to be the most venomous of the spider species – rarely are their bites ever fatal to humans – but they have been known to kill.
Though be warned before you press play on this video – their favourite food source are scorpions.
On the other hand the yellow scorpion which is commonly known as the “deathstalker” is packing one seriously mean piece of poisonous kit in its tail.
These savage characters can kill a human in no time and one sting can produce severe symptoms including fever, coma, convulsion and death.
While we don’t advocate ever putting these two creatures together – if you want to know whose potent venom wins outright crank up the video now.
