The objective of the present study is to describe the functional morphology of venom apparatus of Euscorpius mingrelicus(Kessler, 1874) by using light microscope and scanning electron microscope (SEM). The venom apparatus, situates in the lastsegment of metasoma (telson), is composed of a pair of venom glands and sting. Telson is covered by cuticular exoskeleton as wellas all body, and there are cuticular setae and pits on it as serve sensory organ. The general organization of the venom apparatus ofE. mingrelicus is similar to the other scorpions’ venom apparatus. The venom glands fill in the telson and are a pair and are equalsize. Each venom gland is surrounded by gross striated muscular bundles. The venom is produced in the venom glands, carriedby venom ducts passing through the sting and exiting from the venom pores during the muscular contractions. The venom poressituate both side of the tip of sting and are used for injecting venom. The venom produces left venom gland is carried by left venomduct and exited from left venom pore as well as right. In the transverse section of the sting, both venom ducts can be easily seenby light microscope.
