Uropygids, are commonly known as whip-scorpions and are robust nocturnal predators. There are approximately 108 described species.

Uropygids possess:

  • a pair of long tactile front legs
  • a pair of heavily armoured palps
  • a very distinctive whip-like tail

Whip-scorpions also spray a noxious-smelling chemical mixture from anal glands, as a form of defence.
