Metal-reinforced scorpions evolved to kill
Researchers have discovered that scorpions possess metallic reinforcements in their pincers and stingers, enhancing their hunting capabilities. The study analyzed specimens from 18 scorpion species, revealing distinct layers of zinc and manganese in their anatomy. These findings suggest an evolutionary link between the use of these weapons and the specific properties of the metals that reinforce them.
- ▪Scorpions have evolved to be optimized hunters with various anatomical features aiding in hunting and defense.
- ▪The study found that scorpion pincers and stingers contain concentrations of metals like zinc and manganese.
- ▪Higher levels of zinc were found in thinner claws, indicating a role in durability rather than just hardness.

Rough thicktail scorpion (Parabuthus raudus). Paratuthus scorpions' venom is quick-acting, so they do not need to rely as much on their pincers to capture prey.

Terms of Service and Privacy Policy. Scorpions are optimized hunters, whose skills have been honed through millions of years of evolution. An armored exoskeleton, strong pincers, a poisonous stinger—almost everything about their anatomy aids in either hunting insects, small mammals, and reptiles, or defending themselves from snakes and birds.
