body up to 6" long. Upper body (cephalothorax) often dark.
HISTORY: Venomous. This is the largest scorpion
in the United States, but the least often seen of the three scorpions
spotlit here. Although it is only mildly venomous to humans (unlike the
bark scorpion), its large size allows it to subdue larger prey (e.g.,
lizards). Prefers resting in burrows, often deep underground (up to 8'
deep) where the moisture is higher. See also General
