Vinegar as an Insect Weapon

The cable station, Animal Plant, has a series titled, “The Most Extreme.”  Most recently, there was an episode called “Weird Weapons.” This episode featured a “whip scorpion” that ejects acetic acid out of its “tail” as a weapon. (These insects are also called vinegaroons due to the acetic acid and their smell.) Reportedly, the acetic acid is 17 times stronger than retail vinegar at 5% acidity.
