Umibozu is a sea monster yokai who creates storms and breaks ships. Often appearing at night, the yokai will sometimes request a barrel from sailors, who would give a bottomless barrel so it wouldn’t drown them. In some regions, fishers sacrificed their first catch to the gods to prevent Umibozu’s appearance.

The Alukah, also known as the “horse-leech”, is a giant and many toothed leech that, according to the Sefer Hasidim, takes human and wolf form. It’s possible that the word “leech” actually describes its blood feeding nature, not its appearance, and that the creature is more of a shape-shifting vampire. It can fly using its long hair and may be a descendant of Lilith.
