Definition
A whip-scorpion, also known as a vinegaroon, is an arachnid characterized by its whip-like tail and defensive spray of acetic acid (which smells like vinegar). These nocturnal predators are found in warmer climates. They use their strong pincers (pedipalps) to capture insects and other small prey. Despite their scorpion-like appearance, they are not true scorpions and lack a stinger. They are generally harmless to humans, though their spray can be irritating. Think of them as the sanitation workers of the insect world.
