The clade Thelyphonida consists of two orders of arachnids, Uropygi (whip-scorpions) and Schizomida (short-tailed whip-scorpions). Some sources use the name Thelyphonida to refer only to whip-scorpions rather than the clade. Members of the clade Thelyphonida are mostly small arachnids. The last segment of the abdomen bears a whip-like tail or flagellum, shorter in Schizomida than Uropygi. They use only six legs for walking, the front pair being used for sensing. They are not venomous.
