Answer to Question #91709 in Zoology for Sachin Bhardwaj

Question

Explain the function of gills block

Answer 1

Gills block (operculum) consists of a series of flat bones (operculum, preoperculum, interoperculum, and suboperculum ) that cover gills in bony fishes. These bones support and protect the gills. Moreover, the bones are attached to muscles that allow operculum to move. This process provides the movement of the water through the gills crucial for fish breathing and feeding.
