Well, not really. This story is based on a partial truth: some of the mildest scorpions are quite large. In Arizona, for instance, the desert giant hairy scorpion can give you a painful sting, but the venom has very little effect on humans. Among the smaller types of scorpion, however, the dangerous bark scorpions and non-dangerous stripe-tailed scorpions look very, very similar to the untrained eye. And if you have to choose between being stung by a full-grown mother bark scorpion or one of the tiny babies riding on her back, be aware: Mom’s bigger venom apparatus is definitely more dangerous.
