Researchers examined 18 scorpion species using electron microscopy and X-rays, discovering zinc and manganese in their weapons, with zinc most prevalent at stinger tips and pincers’ cutting edges.
The study reveals metal composition varies by species, with evolutionary trade-offs between pincers and stingers, and slender claws containing more zinc to improve hardness and wear resistance.
Published in the Journal of the Royal Society Interface, the research standardizes metal measurement in arthropods and suggests further studies could explore diet, sex differences, and evolutionary patterns across more species.
