US EditionScientists Discover Scorpions’ Sting Fortified with Metal
Researchers found zinc, manganese and iron concentrated only in the most stressed parts of scorpion stingers and claws across 18 species.
- On Tuesday, researchers published a study in the Journal of the Royal Society Interface revealing that scorpions reinforce their stingers and pincers with metals like zinc, manganese, and iron to enhance durability.
- Using electron microscopy and X-ray analysis on 18 scorpion species from the Smithsonian National Museum of Natural History, the team mapped metal distribution across these arachnids' anatomy to establish a new approach for analyzing arthropod evolution.
- Metals concentrate in areas under stress; stingers feature zinc tips followed by manganese layers, while pincers contain zinc and iron along cutting edges to bolster weapons used for subduing prey.
- Surprisingly, the team noted that slender, weaker-looking claws contain higher zinc concentrations than larger, crushing pincers, suggesting these metals provide vital wear resistance for species relying on speed and agility.
- This discovery helps biologists understand how arachnids adapted to survive for 450 million years, potentially offering a model to investigate whether similar metal enrichment exists in other arthropod weapons like spider fangs.

An international study has shown that elements such as iron, zinc and manganese are not only present in their ‘weapons’, but also determine how they hunt, attack and survive. Research reveals that each species presents a unique combination of metals in its tongs and stings, which directly influences its rigidity, resistance and attack capacity, opening a new line of study on the evolution of these arthropods.
Scorpions Are Basically Tiny X-Men, Scientists Say
Scorpions are already pretty metal. In the metaphorical sense, at least. They are hardcore, cool as heck, and super rad, like spiders if spiders carried a switchblade covered in venom. Well, according to new research published in the Journal of the Royal Society Interface, scorpions may also be literally metal. Or, at least, the most deadly parts of them. Scientists from institutions including the Smithsonian National Museum of Natural History e…
