Scorpions can live from 3 to 8 years in the wild. Scorpions grow by shedding their hard outer shells. The moulting process occurs five to seven times until they reach maturity. At that time, their final exoskeleton forms. The average size of an adult scorpion is 2.5 inches long.
Scorpions have been alive for hundreds of millions of years and are highly adaptable and hardy. Most species of scorpions reproduce sexually. A scorpion can have up to 100 babies in a single brood with the size of the litter depending on the species of scorpion and environmental factors. Scorpions are not hatched from eggs, but are born alive. At birth, the baby scorpions have a soft outer shell. They ride on their mother’s back for 10 to 20 days until their outer shell hardens. At that point, they leave their mother and live on their own for the remainder of their lives.
Scorpions are predatory arthropods. According to National Geographic, they are classified as arachnids, similar to spiders, mites and ticks. Scorpions most commonly live in the desert and can be found on all continents except Antarctica. There are about 2,000 species of scorpion. Only 30 or 40 species are sufficiently poisonous to kill a person.
