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.
When a bee stings, the apparatus becomes detached from the insect leading to its death, hence bees can only sting once. However wasps can sting multiple times and do not leave their sting behind in the skin.
