and one more:
Adult scorpions may have several broods of young. Following an elaborate mating process, which lasts from 24 to 36 hours, the female undergoes a gestation period ranging from 5 months to more than 1 year. The young are born alive in semi-transparent sacs. As soon as the young scorpions free themselves from these thin wrappers, they climb onto their mother's back. Already capable of stinging, the young scorpions leave the mother after several days and begin to fend for themselves. Scorpions reach maturity in a year or more, depending on availability of food.
