A worm that is skilled in fighting snakes
The opimacus is found in some medieval encyclopedias. It is a worm that fights with serpents. It is much smaller and weaker than a serpent, but it wins the fight through skill and boldness. It attacks by attaching itself just below the serpent's head, from where it cannot be removed.
