But specialization, while dangerous if conditions changes (take the poor Cheetah, for example) has its advantages.

What advantage is gained by being prey rather than predator? Herbivore rather than omnivore? A mouth full of grinders with the gut of a carnivore?

"What advantage is gained by being prey rather than predator?

Depends if there is anything to hunt something of your size. While not exactly huge, it would take a T-rex or some substantial to hunt these guys.

Herbivore rather than omnivore? Chopper vs. grinders?

You're an omnivoire. Pretend your a cow. Go try to eat some grass with your nice sharp front teeth. NO HANDS, mind you.
