Scorpions turn into metalsmiths to reinforce stingers for extra strength, study shows

A Smithsonian-led study found that scorpions reinforce their stingers and pincers with metals like zinc, iron, and manganese.

Researchers examined 18 scorpion species using microscopy and X-ray methods to map where the metals are concentrated.

The metal patterns vary by species and are tied to prey capture and defense behavior.

The findings shed new light on how arthropods evolve specialized, biomechanically adapted weapons.
