Waterbears don’t actually have teeth the grinding parts of their mouth are called placoids.  They are the small dark spots that look like stones in a circle.  The pharynx around the placoids expands and contracts in order to chew the food.  The Y shaped structure at the front of the mouth holds the stylets this is what the water bear uses to pierce the food and then it sucks out the middle through the buccal tube. These mouthparts are the ones that are able to be seen in the eggs.
