Scientists have learned that scorpions possess such a sluggish metabolism to allow them to survive in extremely harsh conditions of heat and cold on virtually no food or water. They can live for more than a year without eating, and they are covered with a slick of wax that seals in water. Even in urinating or defecating, they conserve water, releasing nothing but a powder of waste products.
Everything about the scorpion turns out to be extended in time. They take up to seven years to mature, and they gestate their young for up to a year and a half, a pregnancy rivaled only by the elephant. More surprising still, scorpion mothers have something like a mammalian placenta, which nourishes their young internally, another feature unique among invertebrates. The offspring are born live, and then crawl onto their mother's back for another two to six weeks of external development.

He would always leave his hat on the chair by the front door to grab as he left. One morning he was rushing out and grabbed his hat and it was almost on his head before he saw a scorpion in it. Thankfully he shook it out and killed it before it killed him. He was completely bald I doubt he could have survived a sting. It was customary to shake everything, shoes, clothes etc before putting them on because of creepy crawlies but sometimes one forgot.
