The nostrils of the shark help give it an advantage. The shark's nostril contains its sensory that helps to locate its prey or find prey probably miles away. It's also the most sensitive part of any shark.
The basking shark has eyes and nostrils that are quite far apart, with their eyes located on the sides of their head and their nostrils positioned closer to the front of the snout. This unique physical characteristic helps them in feeding on small planktonic prey.
Because they are not actually nostrils nor used for breathing. The two holes on the front of the shark are used for sensing smells, but not for breathing. While the shark swims, water flows through the "nostrils" and along the nasal passage. Inside the nasal passage are folds of skin which are covered in very sensitve sensory cells. These cells enable to shark to "smell" things. For example, a shark can "smell" blood through the water passing into its nostrils, pinpoint the source of the blood and hunt the prey. So, the nostrils are used for "smelling", not breathing.
