The dactillions were a reptavian native to the sinkhole world of Utapau. An avian cousin of the speedy varactyl, the dactillion served as a mount for the native Pau'an and Utai population. Dactillions shared both avian and lizard traits, with long, thin wings and thick, scaled hides. A dactillion's pair of wings allowed it to ride the thermal updrafts in a Utapau sinkhole, and its prominent limbs allowed it to scale the rocky side.
