A recent study led by biologist Sam Campbell at the University of Queensland, Australia, has revealed that scorpions intentionally incorporate metals such as zinc, manganese, and iron into their pincers and stingers. This research, published in the Journal of The Royal Society Interface, examined 18 scorpion species from the Smithsonian National Museum of Natural History. Using high-resolution scanning electron microscopy and micro-X-ray fluorescence imaging, researchers created detailed color-coded maps of the scorpions' weaponry, identifying specific metal concentrations. The findings indicate that the presence of metals is an evolutionary adaptation rather than an accidental accumulation from the environment. Notably, zinc is found in high concentrations at the tip of the stinger, enhancing its hardness and strength, while manganese is prevalent just below this area, contributing to the overall effectiveness of the scorpion's weaponry.
