What zodiac animal does silhouette refer to?

Silhouettes don't refer to zodiac animals.

Silhouette is an art form that highlights the shape of an object by cutting it into black under the backlight. It has nothing to do with zodiac animals. Silhouette pays more attention to the expression of the outline and shape of objects, and does not involve specific animal symbols or symbols. This technique is widely used in painting, photography and other artistic fields, and creates a strong artistic effect through simple forms.
