Merfolk (or Mermaid) are aquatic beings originating from oceanic mythology and fantasy works, typically depicted as mysterious creatures with a human upper body and a fish-like lower body. Common elements include fish tails, scaled textures, shell or ocean-themed accessories, light or water-like garments such as sheer fabrics, coral decorations, and items symbolizing the sea. The overall design emphasizes elegance, fluid motion, and a sense of mystery, creating a dreamy, graceful, and oceanic fantasy visual image.
