These rare and ugly arachnids have squat bodies and a broad cephalothorax. The pedipalps can be long, slender, or short, and possibly sharp depending on the species. The tarsi are sharp. The pedipalps hold prey, while the arachnid's chelicerae tear apart the prey.
All whip-spiders are predacious.
Whip-spiders favor tropical and sub-tropical areas. Some will even appear in caves.
