How many gills are located on each side of the Tilapia What covering protects them?

Number of Gills: Most species of tilapia have four gills on each side. However, a few species may have only three gills on each side.

Protective Covering: The gills of tilapia are protected by a bony structure called the operculum. The operculum is a flap located on the lower side of the fish's head that covers and protects the gills. It also helps to regulate the flow of water over the gills.
