What unique features do spiders with pincers possess that set them apart from other arachnids?

Spiders with pincers, like the camel spiders, have unique features that set them apart from other arachnids. These spiders have large, powerful jaws called chelicerae that resemble pincers, which they use to capture and crush their prey. This distinguishes them from other arachnids, which typically have smaller, less specialized mouthparts.
