S is for Siyokoy - "Siyokoy" are mermen, sea creatures that have a human form and scaled bodies. The Siyokoy is the male counterpart of the Sirena. The lower extremities of the merman can either be a fishtail or scaled legs and webbed feet. They could also have long, green tentacles. They drown mortals for food. Siyokoys have gill slits, are colored brown or green, and have scaly skin, comparable to that of a fish.
