Adapted to arid environments, paravaejovis puritanus is distinguished by its powerful venom which, while not typically lethal to humans, can incapacitate its prey. This species goes through a metamorphosis, starting as live young that ride on their mother's back, relying on her for protection until they undergo their first molt and disperse. As they mature, they exhibit a more solitary nature, usually hunting at night and consuming a variety of insects and small arthropods.
