Answer:
In scoliodon, the respiration is aquatic, i.e., respiration in water and it breathes by means of gills borne in a series of gill pouches on either side of the pharynx. Water enters the mouth and after passing through the buccal cavity, pharynx, gill-pouches and goes out through the gill slits after bathing the gills.
