Scorpions rely predominantly on mechanosensory and chemosensory organs to guide their orientation behaviors. Once sensory organs are affected by the presence of dirt such as clay or prey bodily fluid, scorpions may display a cleaning behavior to reduce or eliminate its influence on their sensory capabilities. In the laboratory, cleaning behaviors of two buthid species, Mesobuthus eupeus (Koch, 1839) and Mesobuthus caucasicus (Nordmann, 1840), and one euscorpiid species, Scorpiops luridus Zhu Lourenço & Qi, 2005 from China, were observed before and after feeding. Moreover, two distinct cleaning behaviors in Scorpiops luridus and three in Heterometrus petersii (Thorell, 1876) (Scorpionidae) were noted for several times during daily activities. Based on these observations, we were able to conclude that different tools and the same tool with diverse applications are used for cleaning the same object in numerous scorpion species.
