- You may also be looking for a group of primitive humanoids who referred to themselves as the Takarians.
Takarans are characterized by a very unusual anatomy and physiology where their internal organs are not as distinct as those of most humanoids. Their organ systems are much more evenly distributed around their bodies, resulting in Takarans having a very high resistance to injury; one Takaran was shown to be capable of walking even with a significantly-sized hole in the center of his chest, although it is unclear how long he could have maintained this if he had been required to survive in this condition for longer. Takarans also have voluntary control over their own physiology down to a cellular level and can place themselves in a form of stasis resembling death.
To Starfleet medical equipment, only the rate of cellular decay could verify whether a Takaran was dead or alive – a slow rate of cellular decay was indicative of a Takaran in voluntary stasis; the rate of cellular decay would be much faster if the Takaran were truly dead-, but this was unknown to Doctor Beverly Crusher until 2369.
