WebbMost sharks rely on ram ventilation, forcing water into the mouth and over the gills by rapidly swimming forward. In slow-moving or bottom-dwelling species, especially among skates and rays, the spiracle may be enlarged, and the fish breathes by sucking water through this opening, instead of through the mouth.

These cells are generally characterized by a high mitochondrial density and an amplification of the basolateral membrane through folding or the presence of an intracellular tubular system. Webb1 jan. 2015 · In both holocephalans (=chimaeras, Order Chimaeriformes) and bony fishes, the interbranchial septa separating the gill pouches are reduced, which results in a single large branchial (opercular) cavity on either side of the buccal cavity containing all the gill hemibranchs ( Fig. 3.2C and D ).
