The most trusted slave of a Goa'uld. Lo'taurs are most often humans, and take many different appearances, usually tailored to the god they serve. They are fit and often possess an appealing physical appearance. It is believed that Lo'taurs are typically human so if their lord's body becomes injured or is in a life-threatening situation, the symbiote can transfer into the Lo'taur to safety. To ensure loyalty, Lo'taurs are often raised from birth for the role. They believe serving their god in such a position is a privilege, and few are willing to risk damaging their relationship with their god, even if they know the truth about the Goa'uld as parasites. Still, they are taught that implantation by a Goa'uld is followed by endless pleasure -- though only reports of pain and torture have come from those unfortunate enough to discover it.
The duties of Lo'taurs are diversified. They are often entrusted with confidential information such as security codes, and have been known to be present at high-security meetings between Goa'uld. Almost all perform small tasks such as serving food and drinks. Though there has not been any evidence to support it, the erotic garments of some Lo'taurs may suggest that some are used as sex partners. Many Goa'uld prefer the opposite sex as their most trusted servants, where other Goa'uld do not appear to care.
Some Goa'uld may have more than Lo'taur at once. If in a position prestigious enough, Goa'uld such as Apophis and Seth have been seen with multiple servants, all of whom may perform the tasks of a Lo'taur. Other Goa'uld such as Anubis appear to have no need for a Lo'taur, though this has not been confirmed.
Baal himself may have had multiple Lo'taurs. A young boy who had served his lord for most (if not all) of his life was in Baal's inner circle, yet mere months later another Lo'taur of the Canaanite god, Shayla, encountered the Tok'ra Kanan and betrayed her master to escape. She had been recaptured for a time, but Baal refused to kill her for fear that she had forfeited crucial information.
