Smithsonian study finds scorpions use zinc and iron for durable pincers.
New research from the Smithsonian shows scorpions contain zinc and iron in their pincers and stingers, enhancing their durability and ability to hunt.
Scientists found that species with stronger crushing pincers had less zinc, suggesting the metal's role is wear resistance.
The study, published in the Journal of the Royal Society Interface, indicates this metal enrichment is likely widespread across nearly 3,000 scorpion species.
