Sting
Definition:
(v. t.) Any sharp organ of offense and defense, especially when connected with a poison gland, and adapted to inflict a wound by piercing; as the caudal sting of a scorpion. The sting of a bee or wasp is a modified ovipositor. The caudal sting, or spine, of a sting ray is a modified dorsal fin ray. The term is sometimes applied to the fang of a serpent. See Illust. of Scorpion.
