The "Hungarian Leech" is the first ever variety leech to be discovered in the history of the world. The Hungarian leech is a close sister of the Bloodsucking leech and nearly identical in appearance, genetics, composition and function to its counterpart. The leech inhabiting those areas featured a distinctly-beautiful pattern on its back and a greenish-brown tint of coloration. Today, Hirudo Hungarian leech continues to be the single most popular leech of Europe. This is one of our most-sold leech varieties!
