I just don't think that they would have much bite force. It would be more like being scratched by brambles.

I wouldn't expect them to have much of a bite now just as I don't expect humans to be able to bite off chunks of living animals by the sheer power of their jaws alone.

Our ancestors had heavier jaws and more protruding snouts but we have broken jaw muscle genes that have reduced our bite force. And our faces are somewhat neotenous.

Anyway, back to Elites - however their ancestors made a living, modern Elites will have had hundreds of thousands of years living with hands and tools and fire so we shouldn't expect impressive jaws.

Nevertheless the jaws they have seem to be inherently bad at biting or chewing. They look better as prey capture apparatus or for making very visible facial gestures.

Maybe they have internal, pharyngeal chewing apparatus or they have muscular gizzards, or very strong stomach acids, or some combination of all of the above.

Their ancestors could have had long necks and pronounced jaw fingers and struck small animals from cover - like a cuttlefish pouncing - or cats (only different ;-) But once they got the whole bipedal-with-hands thing going then their jaws could become reduced and may have been retained for social gesturing.

Or they may be part of their reproductive biology if they reproduce a bit like marsupials. I'm not thinking of pouches per se. I'm thinking along the lines of having undeveloped young that attach themselves to a parent via their jaws which may be the only well developed parts of their bodies at that age.

This link shows that marsupial forelimbs are precocious. This link shows evidence that their reproductive strategy constrains their forelimbs and what they could be used for.
