Summary

Story summary

Scientists at the National Museum of Natural History examined 18 scorpion species and identified metal-reinforced weapons.
Zinc dominates the stinger tip in 15 species, with manganese beneath, while claw edges are enriched with zinc or zinc-iron, lack calcium, and show an inverse relationship between claws and stinger tips.
The findings were published in the Journal of the Royal Society Interface, providing a framework for studying metal enrichment across arthropods.
