Whip scorpions (Thelyphonida or Uropygi)

Flora & Fauna

Thelyphonida is an arachnid order comprising invertebrates commonly known as whip scorpions or vinegaroons. They are often called uropygids in the scientific community based on an alternative name for the order, Uropygi. The name "whip scorpion" refers to their resemblance to true scorpions and possession of a whiplike tail, and "vinegaroon" refers to their ability when attacked to discharge an offensive, vinegar-smelling liquid, which contains acetic acid. Whip scorpions range from 25 to 85 mm (1.0 to 3.3 in) in length, with most species having a body no longer than 30 mm (1.2 in). The vinegaroons use only six legs for walking, with the first two legs serving as antennae-like sensory organs. Vinegaroons are carnivorous, nocturnal hunters feeding mostly on insects, millipedes, scorpions, and terrestrial isopods, but sometimes on worms and slugs.
