Creepy worms: Leech farm in Moscow
Medicinal leeches (Hirudo medicinalis) are bloodsucking aquatic animals that live in fresh water. First employed in Egypt about 2,500 years ago, they have been used as an alternative medicine to blood letting and amputation for several hundreds of years. In 2004, the US FDA approved the commercial marketing of leeches for medicinal purposes. Take a look at the leech farm in Moscow.
