to protect the gills
The scientific name for the gill cover in fish is "operculum." It is a bony flap that helps protect the delicate gills and aids in the process of respiration by regulating water flow over the gills.
That is a hard but flexible cover which, in bony fish, forms the outer wall of the gill chamber. It protects the gills and also plays a major role in the pumping mechanism that regulates the continuous flow of water over them.

Pharyngeal slits are not gill slits. They are filter-feeding organs in non-vertebrates, and are used to strain matter and food from water.
Shark gill slits serve the vital function of allowing water to flow over the gills, where gas exchange occurs. As sharks swim, water enters the mouth and exits through the gill slits, facilitating the absorption of oxygen and the expulsion of carbon dioxide. Unlike bony fish, which have a single gill cover, sharks have multiple gill slits that enhance their ability to breathe efficiently in various aquatic environments. This adaptation is crucial for their survival, enabling them to thrive in diverse marine habitats.
