I'm not sure how far they went into explaining why the Wraith need to feed on Humans but was it ever explained why the Wraith can't feed on other similar animals, like primates, the same way they feed on Humans or is it only something that is biologically unique to humans that they must, and can, only feed on them?
I do know that it has been mentioned that Wraith can consume food by mouth but sucking the life force from something can't just be restricted to Humans?
