I don’t believe they eat humans either. Nothing in any of the movies or the Monette novel , ‘Predator’, suggest any such thing.
Buy looking at the predator’s teeth and other mouth workings; it would seem that he’s not even a carnivore! Well, not in the true sense anyway. If you look at the SSC predator skull, it’s cleat that predators lack carnassials ( As well as a whole lot of other teeth) and it’s the carnassials that make the carnivore!
If they consume any type of flesh, I always figured it would be things like soft bodied invertebrates, Mostly mollusk; snails (land and sea species), cephalopods and shellfish /mussels. Pretty much anything that’s soft, slimy and will go down easy. I can also see them eating things like maybe echinoderms (starfish) small fish and ells. Basically anything they can swallow whole. I seriously don’t think they chew.
I’m familiar with the scene in P2. To me that scene make no sense. I mean seriously, there’s only so much one can do (eat in this case) with six little “teeth”. (Excluding the four mandibles) and I don’t think crushing, tearing and ripping flesh, like that of cows, deer and humans is one of them.

Now an AVP pred is another story, he’s got a few more teeth to work with. Lol
