flag Scorpions strengthen stingers and pincers by concentrating trace metals in high-stress areas.

flag A new study published in the Journal of The Royal Society Interface found that scorpions strengthen their stingers and pincers by concentrating trace metals like zinc, manganese, and iron in specific patterns. flag Researchers analyzed 18 species and discovered these metals are strategically placed where mechanical stress is highest, enhancing durability for hunting and defense. flag This evolutionary engineering is widespread across nearly all 3,000 scorpion species.
