Class 5 humanoid is a humanoid categorization class. It was used by B'Elanna Torres on stardate 48623.5 to categorize the Vhnori decaying bodies found on an asteroid around a planet on that date. Starfleet also had standard resuscitation techniques for Class 5 Humanoids, as stated by The Doctor while reviving a member of the Vhnori species in the sick bay aboard USS Voyager.
