Probic vent



The Probic Vent is a part of Sontaran anatomy. The Probic Vent is a small metallic tube attached to the back of the Sontaran's neck. This Probic Vent is normally used by the Sontarans as a feeding tube during space or time-flight. The Vent is also a major weakness, since a blow to the Probic Vent had knock a Sontaran unconscious or even kill them. The Sontarans, on the other hand, don't find it to be a problem, since it means they must always face their enemy.
