Well I think Jhen Mohran would eat everything that comes to its mouth. Because Delex are most of the time around him he occasionally eats one. But the teeth are more for herbivorous use. I don't think some Delex are enough for such a big monster. Maybe it eats giant cacti that grow in the nearness of the Great desert.

So I think it is more herbivore but occasionally eats some small monsters that come to his mouth.
