Notes on Freshwater Cnidarians, Bryozoans, and Poriferans of North America

While previewing Thorp and Rogers' (2010), "Field Guide to Freshwater Invertebrates of North America", I learned that the phyla Bryozoa, Porifera, and Cnidaria have freshwater representatives, and in North America, no less. I was interested to learn this of sponges and bryozoans, but excited to learn it of cnidarians. It seems that three families are represented in freshwater habitats of North America: Hydridae (hydras), Clavidae (clavid hydrozoans), and Olindiidae (hydrozoan jellyfish).
