The gills push the oxygen-poor water out through openings in the sides of the pharynx. Some fish, like sharks and lampreys, possess multiple gill openings. However, bony fish have a single gill opening on each side.This opening is hidden beneath a protective bony cover called an operculum.he gills push the oxygen-poor water out through openings in the sides of the pharynx.
