The largest of these tiny creatures only reach about ¼ inch long. The body is flattened and teardrop- or pear-shaped. The tip of the abdomen is rounded (not elongated into a stinger like that of a true scorpion). There are 8 walking legs, plus 2 very long, armlike pedipalps ending in pincers, much like the pincers of a scorpion. Body color varies but is usually black, brown, tan, yellowish, or other muted colors. Some species lack eyes.
