According to azcentral.com, scorpions are not built for swimming. However, some varieties of scorpions can live underwater for as long as 48 hours, just like some scorpions can go for as long as a year without eating.
Scorpions are members of the class Arachnida and are closely related to spiders, mites, and ticks. There are almost 2,000 scorpion species, but only 30 or 40 have strong enough poison to kill a person. The many types of venom are effectively tailored to their users' lifestyles, however, and are highly selected for effectiveness against that species' chosen prey.
Scorpions typically eat insects, but their diet can be extremely variable—another key to their survival in so many harsh locales. When food is scarce, the scorpion has an amazing ability to slow its metabolism to as little as one-third the typical rate for arthropods.
This technique enables some species to use little oxygen and live on as little as a single insect per year. Yet even with lowered metabolism, the scorpion has the ability to spring quickly to the hunt when the opportunity presents itself—a gift that many hibernating species lack.
