There's a good deal of "hard vore" situations, I guess. Cyclops/ogres can grab you and take a bite out of ya (nothing graphic, just big/fatal damage then toss you to the ground), evil eyes can chomp you up and munch on you a bit before spitting out.
Also there's a nice, if short, mawshot zoom in of one of the bosses during a cinematic/quicktime event.
That's about all I've seen so far, nothing else seems to swallow you whole like the hydra does though. =/
