Shark interbranchial septum function
In the shark anatomy image, it depicts the beginning half of the shark, including the gills. The shark gills are especially important and were evolved from the chordate pharyngeal gill slits synapomorphy. Like lungs in other animals, gills are essential for sharks to breathe underwater by extracting oxygen from water. The water enters through the mouth, passes into the pharynx, and exits through the gill … Webb(A) Macroscopic image of gill in transversal projection.
