The Glossiphoniidae, the freshwater jawless leeches, [citation needed] or leaf leeches (due to their shape) [11] are freshwater leeches, flattened, and with a poorly defined anterior sucker. [2] The family Glossiphoniidae contains one of the world's largest species of leech, the giant Amazon leech , which can grow up to 45 cm in length. [ 12 ]
Erpobdella obscura is a freshwater ribbon leech common in North America. It is a relatively large leech and is commonly used as bait by anglers for walleye and other sport fish. In Minnesota , live bait dealers annually harvest over 45,000 kg of bait-leeches, raising concerns of over-harvest.

By 1863, British hospitals had switched to imported leeches, some seven million ...
Placobdella parasitica is a species of leech found in North America. [2] Leeches are habitual ectoparasites of vertebrates in aquatic environments. Placobdella parasitica is differentiated from other members of the genus Placobdella by its smooth dorsal surface, simple to complicated pigmentation, and abdomen with 8 to 12 stripes.
The leech sometimes emerges from the water to hunt for earthworms. [4] [7] Like other leeches, Haemopis sanguisuga is a hermaphrodite.
