[2] Limnatis nilotica is native to Southern Europe, North Africa and the Middle East.

The ingested blood is granular in nature, perhaps because the leech has scraped the tissues as it fed.

The volume of blood consumed at any one time is much smaller than is typical for the European medicinal leech, but L. nilotica may stay in place for several weeks, feeding at intervals.

[4] Limnatis nilotica is periodically reported as affecting humans and livestock, entering the host through the mouth, nose, and occasionally through the eye socket, the urethra or vagina.

[2] Two young dogs in Iran with symptoms including anorexia, anaemia, hyper-salivation, retching, and bleeding from the mouth, were found to have leeches under their tongues.
