Burach-Bhadi or Wizard's Shackle is an eel or leech with nine eyes in its head and back, all of which squinted. Found in fjords in the Western Highlands of Scotland, and also reported in Perthshire. It amused itself by winding itself around the hooves of passing horses and drowning them so that it could then suck their blood.
Grotesque giant leeches, these creatures are found in the murky swamps and riverbanks of Britain and Scotland, and will wait for riders on horseback to cross the water. They will then follow the riders using their sense of smell, and drag the horse and the human down into the depths using their coiling bodies. When food is scarce, the creatures have been known to come up onto land or eat members of their own kind.
