One of the more fascinating and fearsome creatures in the world, the scorpion, is even cooler than you might have thought. Research out today confirms these arachnids’ weapons are quite literally laced with metal. Scientists at the Smithsonian National Museum of Natural History and others studied more than a dozen species across the scorpion family tree up close. All of the scorpions had various kinds of metal in their pincers and stingers, albeit in unique, sometimes unexpected configurations. These metals play an important role in helping scorpions hunt and defend themselves, the researchers say. “This study highlights that metal enrichment has strongly diversified in relation to how different species have evolved to use their pincers and stingers,” lead author Sam Campbell, who was a pre-doctoral scholar at the Smithsonian at the time of the research’s completion, told Gizmodo.…
