                        Ok this has been bugging me for the good part of .... well a long time now; the Alien in Alien 3 dosent have the dorsal pipes which the other sub-species have, now i know, the pipes on the back of the aliens are used as a filteration/coolant system to aid the aliens biological survival under the most extreme of conditions. I know this alien in the 3rd film is different in structure but the question I pose is this, how, without those filtering tubes on the back can this alien survive say, in space? or underwater? 
Any ideas?
