Scorpions are not properly insects, but belong with spiders, mites and ticks to the Arachnidae. The scorpions of Palestine are usually 2 or 3 inches long. The short cephalothorax bears a powerful pair of jaws, two long limbs terminating with pincers, which make the creature look like a small crayfish or lobster, and four pairs of legs. The rest of the body consists of the abdomen, a broad part continuous with the cephalothorax, and a slender part forming the long tail which terminates with the sting. The tail is usually carried curved over the back and is used for stinging; the prey into insensibility. Scorpions feed mostly on insects for which they lie in wait. The scorpion family is remarkable for having existed with very little change from the Silurian age to the present time.
