Leeches are represented in North America by four families, two of which were found in the Grand Calumet River: Erpobdellidae, which primarily prey upon macroinvertebrates and zooplankton; and Glossiphoniidae, which either prey upon macroinvertebrates or temporarily parasitize fish, turtles, amphibians, or water birds (Davies 1991).
