Monstrous scorpions are likely to attack any creature that approaches, and they usually charge prey.

Monstrous scorpions are vicious predators that make unnerving scuttling noises as they speed across dungeon floors. A huge monstrous scorpion has a low, flat body: 20 feet long, 10 feet wide* and 2-1/2 feet high**.
*The number includes the scorpion's body and its legs; the actual body width is about a third of the total.
**The number indicates the height of the creature's body; the creature's stinger usually is held about as high off the ground as the creature is wide.
