Scorpions give birth to live young.
Unlike insects, which generally deposit eggs outside their bodies, scorpions produce live babies, a practice known as viviparity. Some scorpions develop within a membrane, where they receive nourishment both from a yolk and from their mothers. Others develop without a membrane and receive nourishment directly from their mothers. The gestational stage can be as short as two months, or as long as 18 months, depending on the species. After birth, the newborn scorpions ride on their mother's back, where they remain protected until they molt for the first time. After this, they disperse.
