Head of a scorpion, coloured scanning electron micrograph (SEM). Scorpions belong to the arachnid family, having eight legs and a body divided into two segments. They have powerful pincers (chelae, left and right) for killing prey. Here, the scorpion's simple eyes (black, centre) are seen on the upper side of the head. This scorpion is from Asia.
