It’s efficiency. They need all the power in snapping shut, not opening hence the muscles do just that. In fact, I think most animals have relatively weak muscles for opening their jaws compared to closing because mastication is so taxing.
Not really related to animals and biting force but I wonder if that's why I find going to the dentist is so awful. It's so hard to keep your mouth cranked unnaturally open for so long.
