Hand-colored scanning electron micrograph of a Skorpion stinger (L. quinquestriatus), by Martin Oeggerli.

This image shows the tip of a venemous scorpion stinger under the electron microscope. Compared to the sharp Scorpion stinger, a medical injection needle is at best a heavy concrete tunnel tube.

Scorpions have eight legs and are easily recognised by the pair of grasping pedipalps and the narrow, segmented tail, often carried in a characteristic forward loop over the back. The tip is connected with a venom gland and injects venom through a pair of elongated holes.

Scorpion venoms are neurotoxic cocktails of numerous individual toxins, which attack different targets within a victim’s body: the animals inject relatively large amounts of pain-inducing chemicals, as well as parazyzing- and pre-oral digestion agents, to ultimately kill or paralyze their prey. Scorpion stingers also equipped with mechano-sensitive receptor hairs to detect fine touches, or movements.
