A water-dwelling yokai depicted in the late Edo-period picture scroll “Bakemono-zukushi Emaki.” It appears as a seashell with an eye and a tail-like protrusion, shown leaping about. No caption accompanies the image and the artist is unknown. Counted among eleven creatures unique to this scroll, it bears a written reading of its name, implying it was not widely known. No specific harm or blessing is recorded; it is portrayed simply as an uncanny presence near waterways.
