Apenas humanos a longo prazo. De blog de Joseph Mallozzi (produtor executivo e escritor de Stargate ):
Halo Luver writes: “1. Are Wraith capable of drawing nourishment from other rational creatures besides humans? Perhaps Asgard or Goua’ld symbiotes?
- Does mass have an effect on how much nourishment a wraith takes from its victim?”
Answers: 1. Although a wraith is able to derive some nourishment from other creatures (like, say, an Asgard), in the long run it will need to feed on humans to ensure its survival. 2. Good question. I think it’s not so much mass but maturity.
Na nota sobre o sabor, mais é revelado em 1x18, "The Gift" :
The Wraith scientist that accidentally gave Teyla and her ancestors the ability to sense the wraith was looking for a way to "make the feeding process more efficient.". This was interpreted by McKay as "more tasty".
