Scylla

A type of monster that lives in the ocean and has a lower body resembling octopus tentacles. Many individuals have personalities that are strong-willed, and a little bit ferocious. They attack ships traveling at sea, stealing food and men. They possess the ability to hide in tiny crevices which one wouldn't think they'd be able to fit in. While they have a strong side, they also have a cowardly nature as well. Because of this, when danger approaches they hide in those kinds of crevices.
