The gills of a fish.
The flap of tissue that covers a bony fish gill is the bony operculum.
opercular gills are found in the class osteichye "bonny fish" who have a operculum. Septal gills are found in chondritchthyes "cartilagenous fish"
The fin located behind the operculum on a perch fish is the Pectural Fins (paired).
Jawless fish are cartilaginous, but they do not have jaws. Class Chondrichthyes, which contains most cartilaginous fish, like sharks, have powerful jaws.
This is called the operculum
It opens and closes like its breathing.
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 gill operculum covers and protects the gills.
The operculum in a perch is a bony flap covering and protecting the gills located on each side of the fish's head. It is part of the fish's respiratory system, helping to regulate the flow of water over the gills for oxygen intake.
OPERCULUM
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.
