Pythons have probably my favorite skull of any animal. The reticulated python has a jaw that is in four movable parts, and the lower two can swing open over 120 degrees. Here are the main parts of a reticulated python skull:
Four, independently moving jaw bones, in case you thought Predator or the Covenant were original: Mother Nature has had them beat for a while! –And look at the angle of those teeth: nothing that goes into that mouth is ever coming out! Here’s a video of a guy getting bitten and his friends have to push the skull forward very hard, then open the mouth, and then pull it away. With these four independent jaw parts, they have the ability to really get their mouths around prey that is much larger than their bodies, like this African antelope:

This is a central row of teeth behind the maxillary teeth on the upper jaw! Here are some better pics to make it harder for you to get to sleep at night:
