What type of creatures squirt vinegar?

Answer 1

From the lore of the Philippines comes the obscure legend of the Pen-an-gglan or Penangallan, a vampire-type creature which possesses a host body rather than converting the person into a vampire. When feeding, the creature conceals its body and the head detaches, pulling upward so as to clear the trailing internal organs which stay with the head. The head and draping organs then fly the short distance to the victim. Penangallan's may squirt vinegar when stabbed or squeezed since they like to soak in it after feeding, as it causes its blood swollen organs to shrink to their normal size.

If you are looking for something more real in the animal kingdom, there is desert-dwelling whip scorpion. It's tail has a knob at its base with a spout which is able to revolve in order to aim in arc, much like a turret gun. The mixture that the scorpion sprays is 84% percent acetic acid, which is vinegar. Hence these scorpions are commonly called "vinegaroons".

Finally, owners of naughty pets squirt vinegar. The will employ a No-No bottle in the futile attempt to alter the behavior of their family members. A No-No bottle is a basic squirt bottle, thoroughly cleaned and filled with 90% water, 10% vinegar(any type). When the very bad dog jumps on the counter to chase cats, she receives a remote punishment of a squirt from the No-No bottle. An interesting note--if the very bad dog has had an encounter with skunks, even after repeated bathing she may have some residual follicular odor. When combined with the vinegar smell post No-No correction, she may smell disturbingly like she's been slathered in a really good BBQ sauce.
