unnnn they only eat one time i have in some place but i dont remember where they only eat in they initial hours of a drone i will look for that that information and i will say to you qhere i have see =D
Look to the Hive the Hell await you in this place, the death is in all place and you dont will survive from the green serpents....
I would think they would, cells can only duplicate so many times before they weaken. Of course that is if you can apply human cells "rules" with the preds'.. :P
Again, this is a thing for us to see in the movies/books, We already know they live hundreds of years, the probably have the same life span as the Yautja
most sites say xenos dont eat as in for food. it has been stated that they 'take in' the nutrients to be later used as resin for the hive. that xeno could have still been in the process of killing the prisoner and not really eating him cuz it is seen wiggleing around and ing about. as far as dying of old age, i havent seen one yet or heard of it in sites, so in that sense your guess is as good as mine. i think they do indeed die after their contribution to the hive is complete, e.g. self sacrifice for the hive, etc.
but hive soldier said that xenos dont eat but i think they eat brains becuz wen they headbite (u Know using the inner jaw) they normaly target the head (thats why its called headbite)
To be or not to be anialated.....thats the deadly question.
Second the things said in the game alien vs predator 2 the xenomorphs are like a living battery ´cause of that i think they never die they dont need food they only die by natural predators and in fights!!!
