Wasp stinger, with droplet of venom

A stinger is an organ or body part found in various animals that usually delivers some kind of venom. It is typically located at the rear of the animal, near the tail (if any). Animals with stingers include bees, wasps, hornets, and scorpions - although the scorpion's stinger is not homologous to that of the other three, but is rather an example of convergent evolution.

In honeybees, the stinger (a modified ovipositor) is barbed, and lodges in the flesh of the victim upon use and tears free from the honeybee's body, leading to the honeybee's death within minutes. The question of how such a trait could have evolved, when it is of such an obvious disadvantage to the individual, is resolved when one realizes that the main function of the stinger is not defense against mammals, but rather inter-bee combat: a barbed stinger can penetrate the chitinous plates of another bee's exoskeleton, and retract safely. Another theory is that since all worker bees are sterile and share the queen's genes,it is in the interest of the hive for the bee to kill herself to protect the fertile queen(who shares her genes and can reproduce).The stinger of the wasp is not barbed, and so can sting mammals repeatedly.

For creatures such as jellyfish, stinger can refer to the tentacles that carry cnidocytes to capture and paralyze prey.

Sting (biology) - Wikipedia, the free encyclopedia (273 words)
A sting (or stinger) is a common term for a sharp organ of an animal or plant that can pierce the skin of another animal.
A stinger is different from other piercing organs in that it pierces by its own action, as opposed to e.g., teeth, which pierce by the force of jaws, or thorns, which pierce by the actiion of the victim.
Any sharp organ of offense or defense, especially when connected with a poison gland, and adapted to inflict a wound by piercing; as the caudal sting of a scorpion.
