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.
The gill filaments are the hair-like structures on the gills which absorb the oxygen from the lamallae. The gill arch, on the other hand, acts as a form of muscle which holds the structures of the gills together. ~Sincerely, A Smarty pants :)
