Yawning is a modified breathing activity that is associated with vertebrate animals that have lungs. It is believed that yawning is a way to introduce more air and oxygen into the lungs so the animal is more prepared for activity; in other words, it's trying not to fall asleep. Since worms do not have lungs, I would say that they probably don't yawn the way we do, but maybe their bodies have a mechanism that helps them enhance the amount of oxygen that they draw in so they don't "fall asleep" when they're supposed to be doing something else, like eating dirt, their favorite activity.
