Some waterbears are carnivores, they eat rotifers, nematodes, protozoa, etc. and some waterbears are herbivores, they eat parts of the moss plant or algae. These are close up pictures of the tardigrade mouth. You can see the mouth, the buccal tube, the stylet supports, the pharynx and the placoids clearly. All waterbears pierce their food with the stylets and then suck out the insides!
