Opercular series in bony fish: operculum (yellow), preoperculum (red), interoperculum (green) and suboperculum (pink)
The operculum is a series of bones found in bony fish and chimaeras that serves as a facial support structure and a protective covering for the gills; it is also used for respiration and feeding.[1]
