Ventilation in bony fish involves closing the mouth and operculum to increase buccal pressure, followed by opening the mouth and closing the operculum to force water over the gills.
La ventilación en peces óseos implica el cierre de la boca y el opérculo para aumentar la presión bucal, seguido de la apertura de la boca y el cierre del opérculo para forzar el paso del agua sobre las branquias.
