Urodacus spinatus is a species of scorpion in the Urodacidae family. It is endemic to Australia, and was first described in 1902 by British zoologist Reginald Innes Pocock. [1]
The species grows to 80–100 mm in length. Colouration is mainly yellow-brown to reddish-brown, with yellowish arms and legs. The male's tail is longer than that of the female. [2]

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.
The taxonomy of scorpions deals with the classification of this predatory arthropod into 13 extant families and about 1,400 described species and subspecies. In addition, 111 described taxa of extinct scorpions are known.
