adult P. nelsoni, P. rubriventris, and P. suwanniensis are almost exclusively herbivorous. Pseudemys concinna are known to retain a greater degree of animal prey in their diet than most species in the genus, but are still predominantly herbivorous as adults. In addition to a variety of algae and aquatic mosses, plants reported in the diets include fanwort (Cabomba), coontails (Ceratophyllum), duckweed (Lemna minor), large-flowered waterweed (Egeria densa), waterthyme (Hydrilla verticillata), water milfoil (Myriophyllum), fragrant water-lily (Nymphaea odorata), southern waternymph (Najas guadalupensis), spadderdock (Nuphar luteum), pondweed (Potamogeton), arrowhead (Sagittaria sp.), and water-celery (Vallisneria americana) among many others.
