We examine the pedipalps of the Australian black rock scorpion using microcomputed tomography, scanning electron microscopy, energy dispersive X-ray spectroscopy, and live pinch force measurements. We recognise 25 muscle groups within the pedipalp and, through documentation of the cuticular microstructure and composition, as well as pinch force values, demonstrate the robust and powerful nature of these appendages that is congruent with the style of prey capture and processing of this sit-and-wait predator.
