The operculum
This is called the operculum
The flap of tissue that covers a bony fish gill is the bony operculum.
The operculum of a tilapia, like in other bony fish, serves several important functions. It primarily protects the gills, which are essential for respiration, by providing a physical barrier against debris and predators. Additionally, the operculum plays a role in the regulation of water flow over the gills, facilitating efficient gas exchange. Lastly, it helps in maintaining the fish's overall buoyancy and stability in the water.
The fin located behind the operculum on a perch fish is the Pectural Fins (paired).
The gills of a fish.
No, agnatha, which includes jawless fish like lampreys and hagfish, do not have an operculum. Instead of a bony cover over their gills, they typically have a series of openings that lead directly to the gill structures. This distinguishes them from jawed fish, which possess an operculum for protection and movement of water over the gills.
The operculum is part of the respiratory system in fish. It is a bony flap that covers and protects the gills, helping with the process of obtaining oxygen from water.
It opens and closes like its breathing.
No, sharks do not have an operculum. Opercula are bony plates that cover the gills of bony fish to help with breathing, but sharks breathe through gill slits located on the sides of their bodies.
the gill operculum covers and protects the gills.
