When we eat something that does not agree with us, our bodies often cause us to vomit up the food that is causing us problems. Once the foul food is expelled from our bodies, we are well on the way to feeling much better. Such is not the case with frogs—they cannot vomit.
When a frog consumes a moth, beetle or other critter that causes it to suffer from gastric they use a far more bizarre technique to alleviate its problem. Believe it or not, they actually expel their entire stomach through their mouth. This behavior is called gastric inversion. Once the stomach is outside the frog’s body, the frog uses its forelegs to clean out whatever caused its stomach distress. When the unwanted material is removed and the frog retracts its stomach it goes on its way.
As much as I dislike vomiting, I am certain I prefer it to gastric inversion.
