When exposed in open, they’ll become immobile & flatten themselves to ground. Another defense mechanism is scattering in all direction. They’ll only use pedipalps as last resort.
Sometimes engage in fights to the death.
They molt every few months when young & once a year when adults.
After molting, it takes 7-10 days to fully harden again.
To have successful molt, they need to stretch out & hang upside down.
Courtship involves male guiding female to deposited sperm packet & inserting it into reproductive opening. Female carries 6-60 eggs in sac attached to abdominal underside, nourishing embryos.
Once eggs hatch, little scorplings white in color & carried on mom’s back for up to a week before 1st molt.
Reach maturity at 2 years old.
