A Siyokoy is an aquatic creature from Filipino mythology.

Overview[]

They can be described as having green scales, webbed hands and feet, and having several fins located around their bodies (similar to gill-man). Unlike a Sirena, Kataw, and a Sireno, who all have human traits, the Siyokoys appear to be animalistic in their physical form and structure. Aquatic animals such as eels, octopuses, rays, squids, and probably sharks often swim along with the Siyokoy.
