actually, even big pythons have very little jaw strength. The power in snakes comes from the squeezing muscles, not the jaws. The dislocating mechanism makes having powerful jaws nearly impossible, because, if they were to chomp down hard, they'd pop their own jaws out of socket, which would then render the powerful muscles useless without a pivot point. Large pythons rely on recurved teeth to hold on to the prey just long enough for it to wrap it's coils around it. I believe discovery channel had a show on the bite force of wild animals and snakes came dead last. Something rediculously low like 30 psi of bite force. (dont quote me on that number, I just remember it being crazy low).
A moray on the other end, has incredibly stong jaw power, AND neck power. It bites down hard, and then twists and shakes to rip the meat clear from bone, or to shatter invertabrate shells. A large python bite would be dangerous because it would be like being stabbed, but not mangling like a moray bite.
