    • n leech An aquatic, more or less parasitic, and blood-sucking worm; a suctorial or discophorous annelid of the order Hirudinea. There are several families, many genera, and numerous species of these worms. Most of them live in fresh-water ponds and streams, some in moist herbage, and a few in the sea. The body is segmented as in other annelids, but the crosslines on the surface are only superficial, and do not correspond to the anatomical segmentation. There is a sucker at each end of the body, that at the head end being armed with biting jaws. The body is usually flattened, broadest toward the tail, but tapering to each end; the color is generally dark, variously mottled, striped, or dotted with lighter or brighter color. The ordinary medicinal leech belongs to a genus known as Hirudo or Sanguisuga, in which there are three jaws in the form of small white serrated teeth which inflict the peculiar triradiate leech-bite. The common brown, speckled, or English leech is H. or S. medicinalis (officinalis), of which the Hungarian green or officinal leech, H. or S. officinalis, is a variety. The European horse-leech is Hæmopis sanguisorba. Another species, Aulastoma gulo, is also called horse-leech. Some leeches attain a length of 2½ feet, as Macrobdella valdiviana. Macrobdella decora is an American leech. Ichthyobdella punctata is a leech found on the whitefish in the Great Lakes. Leeches are used in medicine to extract blood by sucking it.
