Takeaways:

  • New research shows that arthropods such as ants, camel spiders scorpions and bristle worms have adapted to the use of hard minerals such as zin and manganese which give their teeth extra strength for cutting through leaves or prey.
  • The zinc also makes their stingers or mandibles stiffer which is an important that helps maintain sharpness under the pressure of cutting and puncture.
  • This discovery was made using a new type of microscope that used atom probe tomography.
