Their pores and skin is free. It’s coated with a tough and tough materials like sandpaper. Their dry pores and skin was previously utilized by carpenters as a substitute of sandpaper. There are often 5 gill slits on the facet of their necks. This quantity could also be six or seven in some. Their gills do not need lids. Water for respiration is taken from the mouth and pumped by means of the gill slits. Since sharks do not need swimming (air) sacs and are heavy in water, they must swim continuously to keep away from sinking. On this approach, water is pumped by means of the gills by getting into the mouth uninterruptedly.

Because the whale shark swims with its mouth open, the water present is uninterrupted. Their developed vast fins are used like a water wing, continuously lifting the heavy physique up. The digestive system of some additionally aids in swimming. Sand sharks inflate their stomachs by swallowing air to remain afloat. Sharks’ meat is bland and tasteless as physique fats builds up of their livers. The massive and fatty livers of these dwelling within the center depths act as buoyancy organs. Tiger sharks and a few others have been noticed to lie on their bellies and keep on the backside for hours. Their mouths are slowly pumping water into their gills for oxygen.
