Sharks get around without an operculum due to the fact that they instead have branchial flaps. The branchial flaps allow the shark to lay on the sea floor and still "breath" without taking in sand.
No, sharks do not have an operculum. Opercula are bony plates that cover the gills of bony fish to help with breathing, but sharks breathe through gill slits located on the sides of their bodies.
Jawless fish are cartilaginous, but they do not have jaws. Class Chondrichthyes, which contains most cartilaginous fish, like sharks, have powerful jaws.
The operculum
The flap of tissue that covers a bony fish gill is the bony operculum.
This is called the operculum
operculum ( plural ; operculi ) is actually gill cover or lid of a cavity having gills . its major function is to protect gills as well as to move water over gills so that gill may be able to extract oxygen from water . as this lid play an important role in moving water over gills so fishes having operculum can survive even if they are stationary . on other hand fishes lacking operculi have to move continuously to survive .all bony fishes have operculi . best example of fish having no operculum is shark.
The fin located behind the operculum on a perch fish is the Pectural Fins (paired).
