A porpoise is a sea animal that looks like a large grey fish. Porpoises usually swim about in groups.
1 Bees and wasp stings may produce local reactions or systemic (body-wide) allergic reactions. 2  Localized pain, redness, and swelling are the most common reaction to a sting. 3  Severe allergic reactions to stings are known as anaphylactic reactions and may be life-threatening.
The stinger is barbed, so once it pierces the skin, it cannot be retracted. Wasps and other bees do not have a barbed stinger so they are capable of multiple stings. But I think the question here is more on the capability of a wasp or bee being able to deliver a sting after it has died.
