Mastigoproctus is a genus of whip scorpions, also known as vinegaroons, belonging to the order Uropygi. These arachnids are characterized by their whip-like tail and ability to spray a vinegar-smelling liquid as a defense. They are nocturnal predators, feeding on insects and other small invertebrates. They are found in warmer regions of the Americas and Asia. They are generally harmless to humans. Imagine them as the ninjas of the arachnid world.
