“The analysis, published in the Journal of The Royal Society Interface, is the first to statistically examine metal uptake across scorpions while accounting for phylogenetic relationships.”
CORROBORATED
Multiple web search results confirm the publication of the analysis in the Journal of the Royal Society Interface and that the study statistically examined metal uptake across scorpions. While the evidence does not explicitly state it is the *first* study to account for phylogenetic relationships, the consistent reporting of the journal and the scope of the analysis (18 species) strongly corroborate the core claims of the statement.

“The team examined a large museum collection and found that scorpion weapons are selectively reinforced at wear-intensive zones.”
SINGLE SOURCE
While the general idea that scorpions' weapons are reinforced is corroborated, the specific claim that the team examined a 'large museum collection' and found that reinforcement is selectively applied at wear-intensive zones is only explicitly stated in the context of the general research findings, but not confirmed by multiple independent sources detailing the methodology. The evidence is generally consistent but lacks a second independent source confirming the 'large museum collection' aspect.

“Species with large crushing claws and smaller stingers show different metal patterns than those with delicate pincers and more muscular stingers.”

“The study found that the more zinc a scorpion accumulates in its stinger, the less is available to fortify the cutting edge of the pincers, and vice versa.”
PENDING

“Species with powerful, robust crushing pincers tended to show less zinc in those claws than species with long, slender pincers.”
PENDING

“Species with very thin and fragile pincers often carried higher zinc concentrations in the claw edges, apparently preventing fractures by allowing the claws to bend and grasp without snapping.”

“In these cases, zinc is tied to hardness and to resistance against crack formation and propagation under repeated loads.”

“Iron followed a complementary pattern: it was not found in scorpion species with stronger pincers but was more common in species with long, less robust structures.”

“Altogether, the distribution of trace metals maps closely to how species prioritize crushing versus stinging, reinforcing the idea that scorpions optimize their tools like engineers by tuning materials at microscopic scales to match mechanical demands.”
