If the ability to handle those environments wasn't enough, scorpions can go up to a year without eating. They do this by actually slowing down their metabolisms, much like hibernating animals do. There is a difference, however. A scorpion can quickly come out of the depressed metabolic state if they need to, while a hibernating mammal needs time.
It's believed that most scorpions only eat 5-50 times per year under normal circumstances. They simply don't need food more often, because their bodies use up most of the nutrients and they produce very little waste. They usually eat insects, but some species will occasionally eat small mammals or reptiles. Scorpions also eat each other! When they do get a chance to eat, they'll eat as much as possible - up to a third of their body weight - thanks to their food storage organ.
