Scorpions facts

Scorpions are arthropods, they have eight legs, two pedipalps, and a tail with a venom-injecting barb. Scorpions have two venom glands that produce venom used in hunting and self defense. Scorpions do not have bones instead they have an exoskeleton made of chitin, the same thing our fingernails are composed of.
Scorpions are found all across the world. There are over 2,000 different species found on six of the seven continents. They prey on insects, arthropods and in some cases small vertebrates.see more at what do scorpions eat. Because scorpions can live in such hash environments they have adapted the ability to slow their metabolism to as little as one-third the rate for most arthropods. This enables some species to use little oxygen and live on a single insect a year. Even with lowered metabolism, the scorpion has the ability to spring quickly to the hunt when the opportunity presents itself something that many hibernating species are unable to do. Some species can have over 100 viviparous offspring, followed by the young climbing on the mother's back for weeks until first molt and living independently. All scorpions are venomous, they use their venom to paralyze and kill their pray and in self defense. Even small young scorpions can inject you with the same amount of venom as adults.
