Large black eye. Key feature is a double caudal keel. Often found stranded on beaches and mistaken for a baby white shark.

Up to 300 cm. Sharks breathe through 5-7 gill slits. Water runs over the gills, blood in the capillaries pick up dissolved oxygen.

Ram Ventilation: forcing water in through their mouths and forcing it out through their gills. Must keep swimming to breathe. Ex.

Hammerhead sharks Buccal pumping: forcing of water over the gills by opening and closing the mouth. A shark has several pairs of gills on either side of its head, unlike other fish who only have one gill on each side. You probably breathe through your nose and mouth, but a shark only uses its nostrils for smelling.

When peo ple don't want to be seen by their enemies they sometimes wear fatigue suits. Sharks are born with their own special colors to protect them from predators above and below. Learn cool, interesting shark facts like what gills are and how this important biological feature affects all shark species and all the sharks of the world.

Sharks have ruled the oceans for over 400 million years, and their gills are the secret behind this remarkable success. These specialized breathing organs allow sharks to extract oxygen directly from water, enabling them to thrive in aquatic environments without ever coming to the surface. The unique design and function of shark gills reveal fascinating.

Shark gills differ from fish scales in structure. Sharks have five to seven exposed gill slits, while bony fish have five gills covered by an operculum. Sharks and bony fish both have gill slits, but bony fish often possess a protective operculum covering their gills.

Unlike marine mammals like dolphins and whales, which breathe air through lungs and must surface regularly, fish maintain constant oxygen intake underwater through gill respiration. SHARK GILLS Sharks, like other fish, live in the water and use their gills to filter oxygen from the water. When water passes over the gills, a system of very fine blood vessels (capillaries) in the gills takes up (absorbs) oxygen from the water.

Sharks have 5-7 pairs of gill slits located on the sides of their heads. Unlike bony fish, they do not have gill covers. Water must continually flow.
