The gill rakers on fish keep food particles from moving out from in between the gill arches. For filter feeding fish and some suspension feeding fish, the gill rakers function is to trap the food.
Ah, the gill filament, gill arch, and gill rakers are all important parts of a fish's gills. The gill filaments help increase surface area for oxygen exchange, the gill arch supports the filaments and contains blood vessels, and the gill rakers help filter out food particles from the water. Each part plays a vital role in helping the fish breathe and eat, keeping them healthy and happy in their underwater world.
Fish gills are not sharp in the traditional sense. They are delicate structures used for extracting oxygen from water, similar to how human lungs extract oxygen from the air. However, some fish species have gill rakers, which are thin, comb-like structures that help filter food particles from the water. These gill rakers may feel slightly rough or sharp to the touch.
to protect the gills
It is used to cover the gill on the fish.

Angelfish which haa a diet of algae, worms, shellfish, shrimp, and sponges. the other is Butterflyfish which feeds on soft coral,plankton, and small crustaceans.
the gill operculum covers and protects the gills.

Mantas feed on plankton, fish larvae and the like, filtered from the water passing through their gills as they swim. They catch small prey organisms on gill rakers, flat plates of russet-colored spongy tissue spanning spaces between the manta's gill bars. An average-sized manta is estimated to take in 20-30kgs of plankton per day.
The flap of tissue that covers a bony fish gill is the bony operculum.
gill slits
Gill filaments in fish serve as the site of gas exchange, allowing for the uptake of oxygen from the water and the release of carbon dioxide. They have a large surface area with a rich blood supply to facilitate efficient exchange of gases.
