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.
A few insects leave their stinger in the wound, but this is overstated. For example, of the 10,000 species of bees worldwide, only the half-dozen species of Honey bees, (Apis) are reported to have a barbed stinger that cannot be withdrawn; of wasps, all are reported to have smooth stingers.
