The notochord (flexible rodlike structure) of an ascidian (marine animal with a saclike body and siphons through which water enters and leaves) or tunicate (marine animal with a saclike body), more conspicuous in the larva than in the adult and confined primarily to the caudal (tail or hind) region of the body.
The name uropygid means "tail rump", referring to the whip-like flagellum on the end of the pygidium, a small plate made up of the last three segments of the abdominal exoskeleton.
Whip scorpions have glands near the rear of their abdomen that can spray a combination of formic and acetic acid when they are bothered.
The acetic acid gives this spray a vinegar-like smell, resulting in the common name vinegaroon.
