You may have heard from a friend that snakes unhinge their jaws to swallow large prey, but this is not actually true. However, they do have the ability to open their jaws wide, sometimes wider than seemingly possible, because of an extra bone. This allows a slender-bodied snake to consume a large rat, rabbit or larger animal victim.
Their method of eating allows snakes to eat large meals at one time, sometimes sustaining their need to feed for a few weeks.
Once the prey has begun to pass through the snake’s mouth and into the esophagus, the snake’s body is able to pass such a large meal by stretching itself.
