  • Broad mushi
    In the past, it was thought that animals were divided into "furries," kemono , fishes, birds, and literally everything else was mushi . Hence why the term is so broad, even today. You can tell an animal was considered to be a mushi because its kanji will have the 虫 radical. For example, "Frogs," kaeru , and "Snakes", hebi , don't have fur, so they were considered to be mushi.[3]
bagu is normally written with katakana, as バグ.
