==Trivia==
*The Hirudo's name appears to be a bilingual pun in both Latin and Japanese;
**Hirudo is the Latin word for "leech".
***Similarly, leeches make up the subclass Hirudinea in their phylogenic classification.
**Its name may also be a portmanteau of the Japanese words Hiru (蛭), which also means "leech", and Do (道, which may also be read separately as Michi), which can mean "way" or more loosely "doctrine", and can be found in the names of some Japanese martial arts (e.g. Kendo, Judo). Thus, the Hirudo's name can be read as "The Leech's Way" or "'The Way of the Leech".
